THE ENGINEERS' TRANSIT OR 
THEODOLITE 

In reviewing the different parts of the transit and theodolite, it 
will answer our purpose to include them, for the present, under one 
head, using both terms as synonymous — the word theodolite having 
been defined as an instrument of angular measure, possessing two 
graduated circles, normal to each other, which during manipulation 
are set in horizontal and vertical planes respectively. Authorities say 
that it is generally believed that the word theodolite (theodolith) is a 
combination of Oca sight, 080s road, and Aiffos stone and that 
in order to understand this derivation it must be known that formerly 
all supports upon which theodolites were placed were made of stone. 
This meaning, however, seems somewhat ambiguous, and other deri- 
vations have been sought. The etymology of the word is uncertain. 

In classifying there appear two distinct groups of theodolites : the 
simple theodolite, in which the lower clamp and tangential movement 
is neglected; and the repeating theodolite, possessing the double hori- 
zontal movement on spindle and plate, which is the principal feature 
of all complete field instruments made for the engineer at the present 
time. 

The various parts of the transit or theodolite may be grouped 
under the following heads, viz. : 

Begipning from the base-plate we have : 

1 — The tripod connection with the leveling, plumbing and center- 
ing apparatus (Page 14) ; 

2 — The centers (Page 17) ; 

3 — The graduated plate and verniers (Page 17) ; 

4 — The compass and variation plate ( Page 20) ; 

5 — The standards with the vertical arc and its movements (Page 
22); 

6 — The gradienter ( Page 23 ) ; 

7 — The spirit levels (Page 23) ; 

8 — The telescope (Page 24).

1. The Tripod Connection 

An important feature of the Lietz precision-class instruments is 
that they are attached to the tripod by a friction coupling. 

It has been customary to accomplish this, heretofore, in two differ- 
ent ways. One is to attach the instrument to the tripod by means of 
a screw at the base-plate, whereby it remains complete in all its parts 
and is never separated above the leveling screws. This is the method 
employed by the best makers, but it is somewhat tedious and unsafe, 
as every engineer has had occasion to find out. It is often the case 
that the screw will not catch, and there is always a loss of time and 
patience in trying to enter the thread properly. Another point is that 
while turning it on, the entire weight of the instrument rests upon the 
screw thread, with a constant tendency to wear it away. 

The second method of fastening the transit to the tripod is by 
means of the center, making it attachable or detachable above the 
leveling screws. In most cases the foot screws may also be turned 
from the tripod head, but it is not unusual to have them remain as a 
fixed part of it. This mode of coupling seems to us very defective. 
The exposed center is liable to injury in many ways. Dust particles 
accumulate, and it moves with difficulty in consequence, if it does not 
cause fretting. But its greatest fault is the incumbent necessity of 
providing for it what is called the flat center, for turning the upper 
plate. In such an instrument the plates stand too high above the level- 
ing screws, which causes unsteadiness. We believe it to be very 
difficult, if not impossible, to do accurate work with such an instru- 
ment. 

These substantial reasons caused Mr. Lietz to invent the tripod 
coupling, which is regarded as the most successful innovation by all 
who have had occasion to use it. 

Figure I fully illustrates this simple but most effectual device. 
On the tripod head, instead of the ordinary screw, there are 
three jaws. The base-plate of the instrument is swallowtail-shaped on 
the inside (as shown at F), the head having a spring bolt C*. The 
coupling of the two is done by letting one of the grooves on the 
base-plate meet any one of the jaws on the tripod head, when one- 
third of a revolution to the right will make the connection ; at the 
same instant the spring C will fall into a hole in the base-plate, which 
thus prevents any possible disconnection; the latter is effected by lift- 

* The spring C in the latest construction is now placed on the tripod head, between the 
lugs. See illustration, page 98.

ing the spring C and turning to the left. If the tripod head should 
have been worn or bent by accident, the movable jaw D, which is 
worked by the side-screw E (with a large adjusting pin), will again 
give the coupling friction enough to hold the instrument perfectly firm 
on the tripod.

LIETZ LEVELING HEAD 

Quick leveling head attachment. 

Price, extra, $20.00. 



The chief merit of our arrangement is that it enables one to attach 
or detach the instrument to or from its tripod more rapidly, firmly and 
safely than by any other device so far known, and that, too, 
without dividing the instrument proper into two parts, which is 
always injurious to its accuracy and stability, as we have just pointed 
out. To this we may add that it is more durable, easier to keep clean 
and cannot get out of repair. 

The movable jaw, once set for the instrument, need not again be 
interfered with. It is absolutely needless to adjust the friction every 
time the instrument is placed on the tripod. 

We feel quite confident in saying that every engineer who has 
once used this new coupling will readily detect its great merits, and 
will never be without it. All the large-sized transits and levels of the 
Lietz make fit the same tripod head, and are instantly adjusted. 

Leveling Screws 
As these are used more than' any other part of the instrument, 
it is evident that they should be very durable. Those of the Lietz

1 rail A. J_Arl/lZ/ LvUlVlr AIN I surveyors' instruments 

SAN FRANCISCO, U. S. A. 

make possess a very deep thread, rounded a little on the edge, which 
insures a very smooth motion and greater durability than sharp-edged 
threads. The screws are made of composition metal. 

The lower construction of the transit is made with the view of 
affording the greatest steadiness under all conditions. For that rea- 
son the leveling screws are not run through a thin metal disc, with a 
common nut attached for their operation, but an extra strong, star- 
shaped casting, made in one piece, is provided, through which the 
screws are passed and in which they operate. 

The whole construction of this part is intended to insure the abso- 
lute steadiness of the instrument, and to give it rigidity even in a 
strong wind. Any other construction, with a light disc parallel to the 
base-plate, cannot afford that stability which a first-class transit or level 
should possess ; and, since this is one of the prerequisites of an instru- 
ment of precision, we have laid particular stress upon our leveling 
arrangement, which is of the most approved modern design. 

For instruments of the greatest precision, as those used in triangu- 
lation or geodetic work, it may be an advantage to arrange the base' 
with three leveling screws instead of four. These changes will always 
be made upon application. While the ordinary complete transit is more 
compact and of greater utility with four screws, in a specially designed 
instrument for the finest work it will always be well to consider the 
advantages of the three-screw system, universally adopted in European 
instruments. 

Shifting Center for Facilitating Plumbing and Centering. 

All our complete instruments are furnished with shifting plates for 
the purpose of setting them precisely over a point, after having approxi- 
mately done so by the tripod legs. This arrangement is of the greatest 
utility to the field man, and we are convinced that those who have 
adopted it will never again dispense with it. 

While it does not make the instrument less rigid or portable, it 
is so easily manipulated, and becomes a great labor-saving factor. In 
order to center the instrument accurately, two of the leveling screws 
require a slight loosening, when the transit may be shifted upon the 
tripod until the center of the plumb-bob is directly over the point to 
be occupied. The screws are then turned down and the instrument 
leveled up in the usual manner, when it will stand as firm upon its 
base as required.

2. The Centers 

In manufacturing this all-important feature, the very backbone 
of the instalment, too much care and attention cannot be bestowed. 

It is essential that both of these metal axes should have the same 
absolute center as the graduated plate and the horizontal telescope axis, 
whichever way the instrument may be turned. This is accomplished 
by the A. Lietz Company by making this detail a specialty. The care- 
fully chosen material for the vertical axes, the exact method of turning 
and fitting them, and the precision reached in the manner of center- 
ing them, together with the subsequent scrutinizing test to deter- 
mine the slightest eccentricity, have accomplished results as per- 
fect as mechanical means and human ingenuity can achieve. 

Eccentricity has been a source of annoyance and error to the 
engineer, to determine which a number of practical methods have been 
invented and put to use. 

But with our modern transit, if used with ordinary care, this 
source of error has been eliminated, or at least reduced to the lowest 
possible minimum. 

The length of our centers is from 2^4 to 4 inches, according to 
size and style of instrument. To our best belief, this is more than the 
instruments of any of the many different makes possess, having con- 
stantly handled a great many of them in repairing. Yet, by examining 
our illustrations, it will be noticed that with us the limb and vernier 
plates are nearer to the tripod head than in those of other make, owing 
to the judicious placing of the centers, which reach down into the 
base, thus insuring the utmost stability. By comparing our cuts with 
those in other catalogues, the reader will obtain a pretty fair idea of 
what we mean to impress upon him — such a comparison being better 
than any argument by either ourselves or others, based upon mere 
assertion. 

Examine carefully our construction of the centers, and you will 
be soon convinced that our claim for rigidity and stability is fully 
warranted. 

3. The Graduated Plate 

We have now come to the most essential part — the very soul of 
the instrument. It is needless to dwell upon the necessity of an accu- 
rate graduation ; it is self-evident, and it becomes the instrument- 
maker's pride to make it so. 

Page 17 



THE A. LIETZ COMPANY Sl&ig^lWu^ 

SAN FRANCISCO, U. S. A. 

We guarantee our work in this particular as perfectly reliable, 
the graduation lines straight, thoroughly black and of uniform width. 

The plate is accurately centered and free from eccentricity, as 
already explained. Illustrations shown on Pages 62 and 63. 

The horizontal circle is graduated from o to 360 degrees, with 
two sets of figures running in opposite directions (unless ordered 
differently). They are large and distinct, and, to avoid errors in read- 
ing, the figures of these two sets, and those on their corresponding 
verniers, are inclined on opposing slants, thus indicating the direction 
in which the vernier should be read. 

We recommend graduations on a solid silver ring, as that metal 
offers many advantages for the purpose — in fact, its great permanency 
and smoothness renders it the only satisfactory surface for fine gradu- 
ations. However, they are made as the customer desires ; but since 
the additional outlay for silver graduation is only $10, we seldom have 
any difficulty in impressing the purchaser with its advantages. 

It is customary with us to graduate circles so that they may be 
read to single minutes or thirty seconds of arc. We make any 
degree of refinement called for, but our manufactured goods are always 
on hand in the two vernier divisions named. 

The I 'crnier 

This consists of a small sliding scale, movable upon a larger one, 
so graduated that n parts thereof shall include either n -\- 1, or n — I 
parts of the larger scale. The scale may be applied to either straight 
lines or arcs, and aids to determine the smaller divisions of measure 
between the lines on the larger scale. See illustrations Pages 62 and 63. 

A tedious method for measuring small values of arc by means of 
concentric circles was given in the early part of the sixteenth century 
by a Portuguese, Pero Nunez (Nonius), and after him the name of 
nonius is still applied in European countries to what we exclu- 
sively call a vernier here. This term was justly given it in honor 
of the Dutch captain, Peter Werner, who gave to the scale the sliding 
shape in which we now apply and use it practically. Signing himself 
"Pierre Vernier" in a discussion of the "Nonius," written by the 
inventor in the French language and published in Brussels in 1631, 
gave rise to the term we now almost universally employ. 

The graduations on a vernier are usually so made that n divisions 
thereof shall equal n — 1 divisions on the circle. 

It becomes a simple problem to determine the value of n from the 
following equation :

It is customary to graduate the circles of the Lietz transits in 

20-minute divisions, reading to either 20 or 30 seconds on the vernier. 

20 X 60 
The value of n in these cases is : or 60 in the former, and 

20 X 60 



- or 40 in the latter ; or, in other words, 59 and 39 divisions on 

the circle will correspond to 60 and 40 on the vernier respectively. 
Instruments reading to one minute of arc are divided to 30 minutes on 
the plate ; in that case 29 circle spaces are equal to 30 vernier spaces. 

The verniers should be covered with glass to protect them from 
exposure, and for ease in reading they should be provided with ground 
glass shades. 

Our verniers are in such position that the observer need not step 
aside in order to read them, for we place them about 30 degrees from 
the line of collimation. The method of thus placing them has been 
pronounced objectionable, because the size of .the plate level, which is 
at right angles to the line of collimation, and the more important of the 
two, has to be reduced. By examining our instruments, however, 
any one will see that we have attained the object without reducing 
its length, without placing it over the vernier, and without allowing 
it to extend fnaterially beyond the circumference of the plate — all of 
which would be objectionable features. 

The space between the circle and the vernier must appear, through 
a magnifying glass, like a fine black line. No accurate reading can 
be taken if the space appears wider than a mere line of uniform 
thickness under the revolution of the plate. 

Clamp and Tangent Screws 

The lower clamp screw of our transit is of the best devised shape 
and arrangement. It is strong and rigid, and answers the slightest 
touch. 

Page 19 



TUT? A T TTTT'7 /^r^A/T"P A KTV modern engineers' and

SAN FRANCISCO, U. S. A. 

The upper clamp does not come in contact with the limb, but grasps 
the sleeve of the outside center. This is far preferable to the old 
method of pressing together the two plates by means of a screw placed 
at some point on the circumference. 

The tangent screws are single only, and operate in metal cases 
against opposing springs. Great care has been bestowed ih eliminating 
all lost motion of these screws. We; consider double tangent screws, 
working against a tongue, as entirely obsolete. Any instrument sold 
today with double opposing tangent screws may be set down as anti- 
quated and behind the times. It is absolutely necessary that every- 
thing tending to create lost motion must be carefully avoided. While 
adjusting the line of collimation, this source of error becomes very 
annoying, for, in revolving the telescope, the plate is liable to turn 
slightly and the operator is never sure whether the cross-hairs are in 
adjustment or not. 

The arrangement of our tangent screws combine simplicity with 
absolute reliability. Being single, they require but one hand in manipu- 
lation, and their judicious location and spring case arrangement make 
them active and operative at any instant. 

4. The Compass 

Our needle differs somewhat in shape from others, being a little 
smaller in the center than towards the ends, for the reason that the 
magnetic influence is manifested at the ends only, so that all the central 
metal may be called dead weight. Compared with those of other 
makers, the Lietz needle is, therefore, a little lighter, which conditions 
the increased durability of the point upon which it poises. 

Hard steel has the capacity of retaining magnetism longer and 
better than when tempered, and for that reason we have adopted the 
plan of leaving one-half inch on both ends perfectly hard. 

The closest attention is given to the center cap — ■ which contains 
an agate setting — and to the pin upon which the needle rests, for the 
accuracy or sensitiveness depends principally upon these two details. 
These needles possess that degree of sensitiveness required in a high- 
grade instrument. A sluggish needle — one that will hang like a dead 
load — is not fit for the observation of a reliable azimuth. 

The center pin must occupy the true center of the graduated circle, 
and must stand normal to its plane. We utilize precise instruments 
with high magnifying power to obtain the absolute true position of 
the pin, in order to avoid all errors due to eccentricity. 

Page 20 



?t?.Px^R E s^|g^^ THE A. LIETZ COMPANY

The lifting arrangement is applied with the view of raising and 
lowering the needle gently and gradually, as any sudden drop to the 
pin, or any quick action of arresting its motion, is sure to cause a 
rapid wearing of the point and the cap. 

The Compass is divided into 30-minute divisions, and numbered 
from o to 90 degrees in each quadrant from the north and south points. 
This is done to conform with the usual practice of surveyors in this 
country to record bearings in the four quadrants. But any desired 
method of numbering the compass, either from o to 180 degrees, or 
from o to 360 degrees, may be had upon application. 

In order to record at once the true bearings in the field, instead 
of the magnetic, the instrument can be provided with a variation plate, 
1. e., an arrangement for laying off the local deviation of the needle 
by a movement of the graduated compass ring, so that the indicated 
course of a line shall show at once its relation to the true meridian. It 
is so made that the variation may be laid off with precision to the 
minute, by the aid of the instrument's vernier. 

This is done in the following manner : 

Having set the plate vernier to zero, adjust the instrument and, 
with the aid of a good reading glass, place it in such a direction that 
the north end of the needle shall point to the zero of the compass ring, 
which latter must coincide with the little pointer provided for that 
purpose. Having carefully set the instrument thusly by means of the 
lower clamp and its tangent screw, which can certainly be done to the 
nearest minute of arc, we release the clamp of the plate and proceed 
to lay off the amount of the local deviation of the needle in degrees 
and minutes by means of the plate-vernier — to the right if the variation 
be east. The instrument is now again in a fixed position, the telescope 
pointing to the true north, or as much to the left of the needle as the 
magnetic variation is east. We now proceed to turn the ring until its 
zero shall coincide exactly with the north end of the needle, when every 
subsequent reading of the compass, in any position, will indicate the 
bearing of the vertical telescope axis from the true meridian. 

This simple little device is fully up to the standard of accuracy 
required, for with care in setting the needle we can always obtain 
results correct within the nearest minute. We find that by this method 
the additional vernier, usually placed inside of the compass ring, be- 
comes superfluous, as the plate and vernier of the transit are perfectly 
capable of taking care of the duties of this unnecessary accessory.

The variation plate has proven a great labor-saving device, as the 
observed courses require no reduction to the true meridian subsequently. 
It is now almost universally called for; and for those practitioners 
with whom land surveying is a specialty we should, by all means, 
recommend it as an indispensable feature. 

5. The Standards and Vertical Arc 

The standards are so constructed as to give the maximum support 
to the telescope, commensurate with the size of the plate. They are 
light, but rigid and strong. 

To avoid unequal expansion of the metal in the standards by 
exposure in the hot sun, which has a tendency to elevate one end of the 
telescope axis and to depress the other, vitiating the adjustment, they 
are now what we call "Torchon" finished. This finish, being a non-con- 
ductor of heat, reduces to a minimum this source of possible error, 
which, in very sensitive instruments, is of sufficient moment to be 
guarded against. Other parts of our instruments are also finished 
in the same manner, particularly Level telescopes, which we shall have 
reason to mention again hereafter. 

The bearings for the telescope axis are made with extra care and 
attention. 

The axes of the Lietz transit telescopes are cut to conical or 
cylindrical bearings, which is a feature altogether preferable to the cor- 
rugated shape frequently found in surveying instruments. The advan- 
tage of the former is very evident, in that there is less friction than by 
any other contact; and, in addition to that, it affords a much finer fitting 
by reason of its shape. But it is very essential that the hardest metal 
should be used for this purpose, as a material of insufficient hardness 
would soon wear, and the axes would become elliptical. 

One of the standards is supplied with an adjusting device to 
regulate any inaccuracy in the motion of the telescope in -the true verti- 
cal plane, when the centers of the instrument stand vertically. 

One standard carries the arc for observing vertical angles, which 
may be either a full or a half-circle, as the customer desires. It is 
usually made to read to minutes, but may be graduated finer if so 
ordered. A clamp and tangent screw are provided on the right-hand 
standard, which are made like those already described for the hori- 
zontal movement. Every part of the vertical measuring apparatus is 
strongly and accurately made and fitted, to insure the best results in 
its practical application.

6. The Gradienter 

The head of the tangent screw of the vertical arc movement is 
made somewhat larger, properly silvered and graduated into a number 
of equal parts on its circumference, the thread of the screw being cut 
with great precision, so that its revolution may be accurately recorded 
by the divisions of the micrometer head. See illustration Page 65. 

One complete revolution of the screw corresponds to B /io OI a foot 
of difference in level in 100 feet. Since the head is divided into fifty 
parts, it follows that one division equals a difference of y i00 of a foot 
in 100 feet. 'We can also furnish with a moveable head admitting a zero 
netting. 

With this attachment grades may be established very quickly. It 
is only necessary to set the screw head to zero, level and clamp the 
telescope, and turn the screw up or down as many spaces as there are 
hundredths of a foot of rise or fall in one hundred feet of the grade 
to be laid out. With the small scale over the screw thrown back, the 
gradienter is used as an ordinary tangent screw. It is one of the most 
useful accessories, is easily applied, and adds nothing to the weight of 
the instrument. 

This attachment is also useful in the determination of horizontal 
distances, it being obvious that the difference in rod reading between 
two complete revolutions of the screw will indicate at once the distance 
of the rod from the observer. Where the ground is level, or nearly so, 
the simple difference in rod reading will suffice; but when this is not 
the case, the necessary corrections will have to be applied to obtain the 
true horizontal distance. 

7. The Spirit Levels 

We nave already noted that for our purposes we use the very 
best article obtainable. 

An instrument of precision, capable of measuring delicate differ- 
ences, requires delicate and sensitive levels. This is so obvious that we 
ought not to call attention to it here, were it not for the fact that we 
are frequently approached by surveyors who wish to impress upon 
us the idea that this or that make of instrument met with their approval 
because its bubbles would stay in place when once adjusted. For this 
reason we want to repeat that it is no claim for superiority of a spirit 
level because it works sluggishly. An engineer in the field must know 
when his instrument is absolutely level, and its bubbles should indicate 
to him at once when this is not the case. If they do not do so, then 

Page 23 



THE A. LIETZ COMPANY a$v^oKll5rV ND 



• INSTRUMENTS 



SAN FRANCISCO, U. S. A. 



the instrument does not come up to the required standard of a precise 
tool. It would hardly do to place a carpenter's level on a transit, yet 
we have no doubt that its excellent qualities of remaining stationary 
would find admirers. 

There is, of course, a limit to the degree of sensitiveness, and that 
we never exceed, adapting it in all cases to the work demanded of the 
particular instrument in hand. 

Our levels are ground to the proper curvature, and each is care- 
fully tested upon our level tester before it is attached anywhere. 

The telescope can be fitted with reversible level if desired. 

8. The Telescope 

We have now reached another most essential feature of the instru- 
ment — that which may be compared to the head of the body, containing 
the delicate organ of sight — the lens. 

The Lenses 

We have already called attention to the fact that our optical acces- 
sories are the finest made and that we take great pains to obtain the 
best article for the purpose. 

Without going into the detail of optical mathematics and formulas, 
that can be readily found in any text-book on physics, we all know that 
it has been the constant aim to produce lenses as free from spherical 
and chromatic aberration as it is possible to make them. The lenses 
of the Lietz telescopes are an achievement in theoretical and practical 
science of which it would be interesting to make some explanation had 
we the space to give to it. 

The Eye-Piece 

Two forms of ■ eye-piece are known, the one giving the erect 
vision' of the object, the other an inverted image. The latter admits of 
a greater amount of light and also allows a longer focal length to the 
object glass, thereby correcting spherical aberration besides increasing 
the magnifying power. 

We have always considered this inverting form the more advan- 
tageous of the two ; and we are convinced that if our engineers would 
accustom themselves to its use, it would finally be preferred ; but we 
can appreciate the greater convenience of the erect form when the in- 
strument is used by many men.

The optical powers of the telescope are in perfect keeping with 
the accuracy of the centers, graduation and spirit levels, insuring a 
complete reliability and harmony in every part of the instrument for 
the most refined surveying work. 

The eye-piece (always erect unless specially ordered) is so arranged 
as to permit its easy removal, if necessary, by simply unscrewing it. 
In replacing, it should always be well tightened up. It is movable in 
and out by a revolving motion, turning the cap about one-sixth of a 
revolution backward or forward, comprising the most practical and 
efficient method. 

We shall now describe in a few words the mechanical construc- 
tion of its other parts. 

Other Parts of Telescope 

The slide, to which the object is attached, fits directly in the out- 
side or body of the tube. Particular attention is paid to this part to 
prevent even the slightest shake, and still procure an equal and sure 
motion, which is absolutely necessary, as no true adjustment of the 
line of collimation is possible otherwise. The motion is given by a 
spiral rack and pinion. 

The sliding tube is protected from dust and dirt by an exterioi 
metal cylinder, called the slide protector. 

A sun shade is provided for the objective, which should always 
be attached, as the telescope, when focused to mean distance, is bal- 
anced with it; and a cap is provided for the protection of the objective 
when not in use. 

The cross-wire frame is suspended in the tube by four capstan- 
headed-screws, by which it is adjusted, the frame being so constructed 
that the cross-wires cannot be torn, in case the adjusting screws are 
tightened too much. 

The spider web used for our instruments is properly treated to 
avoid all twist, and to prevent its lengthening and becoming crooked 
in damp weather ; it cannot become loose, as it is well secured. 

For mining and tunnel transits we can provide proper means for 
illuminating the cross-wires — an arrangement that is readily supplied 
upon application. 

Quite a number of glass diaphragms have been cut by us for. the 
United States Coast and Geodetic Survey. Instead of the spider webs, 
a small disc of very thin glass is fastened to the diaphragm, on which 
fine lines have been drawn with a diamond. It is readily seen that 

Page 26

SURVEYORS' INSTRUMI 



these cannot get out of shape, and for stadia measurements we think 
them of great advantage. The only drawback is that small particles 
of dust may settle on the glass disc, and, as they are in the focus of 
the eye-piece, they will be constantly visible to the observer. 

We make no extra charge for putting those diaphragms into our 
new instruments, if ordered in time. 

Stadia hairs are placed in our transits (and levels) when ordered. 
We have superior facilities for setting them with great precision to 
any desired ratio between distance and rod reading. It is customary 
to place them so that they shall read I foot on the rod for a distance 
of ioo feet, and to this measure we always have them in our stock 
on hand. 

The stadia hairs may be fixed or adjustable. We advise the fixed, 
as they are less liable to change their distance. In an adjustable set 
the observer is never certain that the position of the wires has remained 
unchanged. We have constructed a delicate optical and mechanical 
apparatus for fixing stadia hairs accurately to any proportion ; and 
by means of our powerful telescope, which has superior optical quali- 
ties, we can safely say that, with proper care and a little experience 
in that method of measuring, very satisfactory results may be obtained. 
The facilities for measuring across inaccessible places, and the speed 
with which it enables one to get distances, has brought this method into 
deserved prominence with our engineers. For topographical surveys 
it is indispensable. 

When purchasing a new instrument, it is advisable to get one 
that has fixed stadia wires, which increases the cost only $3, while we 
charge $10 to put them into a transit or level sent to us subsequently. 

In sighting with the telescope it is of considerable advantage to 
have it reversible, and our transits are made so as to allow this free 
revolution in a vertical plane. The telescope balances accurately when 
in focus to mean distance, the friction in the bearings being shaded to 
such a degree of nicety that it shall neither work too hard nor too 
loose — a feature which ought to have very close attention. 

General Remarks About Telescopes • 
When selecting or examining an instrument, the engineer should 

be particularly careful to test the qualities of the telescope. 

It should have sufficient magnifying power to correspond with 

the finer qualities of the graduation, axis, centers, spirit levels, etc., of 

the instrument. There can be no doubt that the excellencies of each 

detail must compare with that of any other.

Now, by using a low-power telescope, the defects of an inferior 
instrument may be hidden, or left undiscoverable, and for this reason 
they will always be found in articles of lower grade. Had such an 
instrument lenses of sufficient magnifying power, the defects would 
become apparent to the engineer at once. We lay the greatest im- 
portance upon these facts, and for this reason call particular attention 
to them. Scrutinise the optical abilities of the telescope, and you will 
obtain the character of the whole instrument. 

An engineer should be careful to convince himself of the real mag- 
nifying power before making a purchase. He will find it much to his 
interest to do so. 

We have found that the power of first-class instruments should 
be about twice as many diameters as the length of telescope expressed 
in inches. In inverting telescopes it may be materially increased, which 
shows again that they are of considerable importance in very high 
grade instruments. 

In another place we have added a practical method for finding the 
magnifying power of a telescope, to which we would advise our 
engineers to give some attention, and to make use of when about to 
choose an instrument. 

We have already pointed out the importance of perfectly center- 
ing the lenses, especially the objective. If this is not properly attended 
to, the adjustment can never be perfected for long and short distances. 

We have heard many complaints of various makes about the 
change in adjustment, and after careful examination we have found 
that the adjustments remained intact, but that the fault lay in the 
objective, which had not been correctly centered. We take great pains 
to center our object glasses perfectly, and to insert the lenses in such 
a manner that if taken out they may be replaced in the old position, 
which is secured by a notch and a pin. It is not advisable for engineers, 
however, to take these lenses from the cell, as their cleaning may be 
effected without removing them. 

Reverting again to the magnifying power of telescopes, it may 
be asserted that an increase thereof reduces the field. This is no defect, 
if the size of the latter is retained large enough to admit of stadia lines 
so placed as to read I :ioo. We often leave the field much larger, 
however, in which case there appears just a slight dimness at the ex- 
treme border; this is unimportant, for it does not retract any of the 
virtues of the glass, and possesses, if anything, an advantage of finding 
an object more readily.

The quality of some of the telescopes of our best makers has 
often been questioned by competent engineers on account of a peculiar 
haze ascribed to the glass. This was found to be caused by a small 
film of moisture, which settles between the crown and the flint, and is 
not visible to the naked eye. We have been convinced, by advising 
with our optician, that the crown and flint glasses should always be 
connected with balsam. This does not decrease the amount of light, 
as formerly thought, but, on the contrary, it has advantages of clear- 
ness, in that it prevents foreign matter from settling between the lenses, 
which always destroys the image ; the refrangibility, too, is under more 
favorable conditions in the balsam. 

Extra Accessories for the Transit 

There are a number of additions made for transits used for special 
purposes, and these we keep on hand, and supply them when called for. 

For laying off right-angles, for instance, we can make any pro- 
vision, if the customer will order it in time. In fact, any of the 
accessories, not usual in the ordinary complete field instrument, will 
be made as an extra if our patrons will notify us. 

For the solar attachment we provide a block with a thread on the 
telescope axis to receive these beautiful little apparatuses of which 
complete descriptions will be found later. 

The Finish. 

This is made to give the instrument an elegant, tasteful appear- 
ance, without adopting a color glaring to the eye. Our instruments 
are finished in an elegant leathered effect, but may be bronzed to the 
special taste of the purchaser, if he chooses to order it. 

Size of Transit. 

The dimensions and proportions of the several parts of the transit 
are given in Part II of this catalogue, where the different sizes and 
varieties of instruments made are described more in detail. 

Packing. 

This is not at all an unimportant feature. Our transit is easily 
taken from the tripod by means of the Lietz friction coupling already 
described, and set upon a wooden slide, to which it is fastened by means 

Page 29 



TTTUT? A T TTTTTT PHA/fPAMV modern engineers' and 
1 rlJli A. Lyl-C/lZ/ liVJlVlrArN I surveyors' instruments 

SAN FRANCISCO, U. S. A. 

of two thumb screws and wooden clutches — a manipulation requiring 
but a moment's time. Nothing is taken from the instrument except the 
shade — it remains a complete whole from the base-plate to the top of 
the telescope. The board slides into the box with the transit in an 
upright position, with the clamps secured to keep it from turning. An 
extra place is provided for the solar attachment, if there be one. The 
door may then be locked, and the instrument is absolutely safe, with 
the least effort of packing and adjusting in the box. 

Rubber cushions are provided at the bottom of the case, to take 
up any sudden jar or jolt to which it may be exposed during transpor- 
tation. 

The Tripod. 

We have adopted the new form of split leg — a construction which 
combines the greatest stiffness and strength with the least weight. The 
old form of the heavy solid leg has long since been abandoned, and we 
no longer make such a tripod, unless specially ordered by some con- 
servative customer, or for very small instruments. We aim to reduce 
the weight of everything, without sacrificing steadiness or strength in 
any particular, and that the split leg meets these conditions better than 
the solid one must stand to reason. 

The very best white ash is chosen and carefully worked. Instead 
of fitting the leg between two brass cheeks, we fit one cheek in the 
leg. In the older construction it frequently happened, in drawing the 
bolts closer to tighten a loose leg, that the cheeks would spring the 
plate, or weaken the screws that hold it. This is entirely obviated by 
the new arrangement of these parts, for the tightening can no longer 
affect the plate in the least. While in the former the leg would only 
fit at the lower part of the cheeks when drawn in by the bolt, it will 
always fit the whole surface of the cheek in the plan we follow, and 
after ten years' use it will be just as steady as when new. 

The shoes are made on a gradual taper to a sharp point, and 
securely fastened to the leg. They are provided with a projection for 
pressing upon with the foot when setting up. 

The large transit and the level fit the same tripod — in fact, any 
Lietz instrument may be readily fitted upon the tripod we manufacture, 
for the adjustment of the friction coupling allows a perfect accommo- 
dation to any slight variation in the parts of the base-plate.

LEVELING INSTRUMENTS 

I.ietz levels are manufactured in two different types, which we 
aim tn keep constantly in stock, the Y-level and the Dumpy level. 

In the manner of making these instruments, much that has been 
said of the transit will hold good here, and need not be repeated. 

The three main qualities to be secured in a level are : stability, a 
sensitize bubble and a powerful telescope. 

To secure the first, we need only refer to the solid construction 
of the star-shaped casting through which the leveling screws operate, 
already described in speaking of that feature in the transit. The Lietz 
coupling, too, plays an important part here, for we can make the tripod 
connection absolutely rigid. 

The center, or spindle, is almost three and one-half inches long, 
and is continued through the damp up to the bar, which enables us 
to bring the center of gravity as near as possible to the tripod head. 
Great care is exercised in fitting the center to the socket, and, being 
made of the hardest composition, it must be apparent that it is an 
utter impossibility to wear out these parts, even by fifty years' constant 
use. The liability of bending the spindle, so common an accident with 
instruments having soft centers, and the fretting of the same, also 
likely to happen at times, is altogether avoided. 

The reasons for having a sensitive bubble have also been carefully 
set forth heretofore. Accurate work cannot be done with a sluggish 
bubble. No matter how much the virtues of the staying qualities may 
be extolled by some men, they are not fit for refined work if they do 
not answer the slightest touch of the leveling screw. If you can give 
a screw a twist or two before the bubble loses its peaceful equanimity, 
the work in hand would not be likely to inspire any great confidence. 

Our level tube* is curved, so as to give for every two minutes of 
arc a one-inch motion of the bubble. A refined level of this character, 
however, will only do good service in an instrument having perfect 
steadiness and a powerful and sharply defining telescope. If placed 
in a level so constructed as to be topheavy, or in one whose center is 
frequently exposed by being a part of the tripod head — and therefore 
liable to collect dust both on the cone and in the socket, introducing 
sources of error after every detachment — then it will indeed prove 
very annoying, should an active bubble accompany such an instrument.

These structural defects are probably the cause why many of our 
engineers are prejudiced against sensitive levels, and prefer a sluggish 
or dull one. We can only assure the reader again that a lively bubble, 
even if a little out of center by reversing the instrument, will still 
accomplish better results than an inactive one — one that gives the 
instrument an appearance of steadiness, which in reality it is far from 
possessing. An engineer only deceives himself if he trusts to a slowly 
acting level, which gives apparent satisfaction by concealing the errors 
that a sensitive one would soon indicate. A precision instrument 
never suffers by having its qualities exposed by a high-grade bubble. 

The level telescope should have power and definition. It is hardly 
necessary to make that statement, after all that has been said on this 
subject in a previous chapter. It has been our earnest endeavor to 
obtain these results, without increasing the dimensions of the telescope 
and the other parts of the instrument, beyond the proper limits for 
steadiness and portability. A length of eighteen inches we have found 
to give the most advantageous results. Experience has shown us, that 
although an increased length adds to the magnifying power, it would 
only be of value if the other parts of the instrument were enlarged 
in proportion, which, on the other hand, would make it too heavy for 
convenience in carrying and offer more surface to the wind, thereby 
reducing steadiness, we believe that with our 1 8-inch level even the 
most extensive requirements in engineering are fully met. 

Our new and improved eye-piece, and the use of an objective of 
proper proportioned diameter, enable us to obtain a magnifying 
power of 33. An increase of diameter adds very little to the weight 
of the telescope, and does not require a longer bar and larger plates, 
as an increase in length necessarily would, to retain steadiness. An 
aperture of l^i inches, used to its full value, affords a high illumina- 
tion with the above-mentioned power, as the tube is large enough to 
let all the rays proceeding from the object glass pass through to the 
field of view. 

The diameter of the aperture of the object glass divided by the 
power, gives the diameter of the pencil of light entering the eye. In 
our telescope we obtain, therefore, iy% -f- 33 = y, 4 of an inch, which 
shows that power and brightness are in, accordance with optical law. 
To force the power beyond these limits we cannot conscientiously do, 
as that would be allowable only under certain circumstances — such as 
a perfectly clear atmosphere with a strong illumination of the object.

The collars, upon which the telescope rests in the Ys, are made of 
the hardest bell metal, and admit of a position in cither direction, that 
is. the telescope is reversible. The very first requisite is that these 
collars must be of exactly equal diameter and perfect cylinders. If this 
be not the case, the line of collimation will not be parallel to a tangent 
of the bubble's curve at its highest point, when the latter indicates a 
horizontal position, and, for this reason, a true level cannot be obtained 
with such an instrument. 

It is very often believed that in the course of adjusting the 
V-lcvcl. by reversal of telescope and revolving on center, the bubble 
will indicate any inequality of the collars, but this is by no means true. 
If the Ys are both filed out to the same angle (this is generally the 
case, or at least very nearly so. as most makers file them out by means 
of gauges), the inequality of the collars may be quite appreciable, and 
yet the instrument will be adjustable in all its parts ; in other words, 
it may be so adjusted that the bubble on all reversals in the Ys and 
revolutions on center, will always give the same reading at both ends, 
that is, indicate a true horizontal position. A final test is necessary, 
therefore, after the instrument is properly adjusted, to ascertain the 
equality of the collars. This will be mentioned further on under the 
head of adjustments. 

Similar causes for error are introduced if a particle of sand lodges 
between the collar and Y, which illustrates the necessity of keeping 
these parts free from all dust and dirt. 

It is readily demonstrated to what considerable difference any 
slight inequality in the diameters of the collars may give rise to, but 
the space here will not permit of a mathematical discussion of the 
subject. 

We have carefully explained this defect, owing to the conviction 
on our part that it is a much more common one than is generally sus- 
pected. Numerous cases have come under our observation, where this 
fault existed in a remarkable degree. And in the perusal of many 
works on engineering and surveying, we have noticed very few that 
call attention to this material defect, and still less that give a correct 
test for it. 

We are aware that accurate leveling may be done with a level out 
of adjustment, if the utmost precaution is taken to have equi-distant 
fore- and backsight. But looking at it from this point of view, why 
not use the dumpy level then, instead of the more costly Y-level? 

The Finish is made to give the instrument an elegant appearance,

and yet obtain all the qualities alluded to in a previous discussion of the 
same subject. The telescope is "Torchon" finished to avoid that 
unequal expansion of the metal heretofore mentioned. This finish is 
of a color pleasing to the eye, is applied so that it remains intact for 
a long time, and if somewhat worn after a long period of exposure, it 
can be readily reapplied without difficulty at a trifling expenditure. 
This finish is a modern feature, and one that is so universally pre- 
ferred, that we have no hesitation in recommending it to our patrons 
as worthy of their consideration. However, we also keep in stock the 
bronzed and lacquer finished level telescopes, so that the customer may 
have his choice in the matter. 

The level telescope is supplied with a slide protector and with a 
sunshade ; the latter should always be put on to balance it evenly. A 
cap is also provided for the objective and a shutter for the eye-lens. 

In all other matters the transit details obtain here also. 

Fixed stadia wires can be supplied, set to read 1 :100, for which an 
extra charge is made if ordered, unless included in price stated. 

The center movement is checked and regulated by a clamp and 
tangent screw, exactly similar to those of the transit. 

Other useful accessories are attached, but any feature not usually 
found in the Y-level, must be ordered beforehand. 

We are likewise in a position to make, but upon order only, levels 
of precision for the most exact work that the geodetic surveyor is 
called upon to perform. These are provided with all the delicate 
details that such an instrument must possess. We invite correspond- 
ence upon the subject of geodetic instruments, and will cheerfully 
furnish prices after consulting with our patron upon the nature and 
character of the instrument required. 

The packing in the case has been made so as to assure safety in 
transportation, with the least trouble and inconvenience to the operator. 
The level is taken from the tripod by a third of a revolution of the 
base plate, which undoes the Lietz Coupling. It is let down to stand 
upright in the box, when the closing of the lid holds everything firmly 
in place. In all minor details the level box is similar to the transit 
case, every means being employed to insure absolute safety. 

The Dumpy Level. 

In this instrument the aim has been to construct it in such a 
manner that it shall be as compact as possible by dispensing with 

Page 34 



§K$y THE A. LIETZ COMPANY 

S \n i u INCISCO, U. S. A. 

certain features of the Y-level, not absolutely necessary in order to do 
good and reliable work. 

The principles governing its construction are the same as those 
that obtain in the more elaborate Y-instrument. 

The telescope is permanently held by two vertical arms attached 
to the level bar, and cannot be taken therefrom. The level tube rests 
upon these anus, over the telescope, and is also fixed. The telescope 
tube is thereby brought as close as possible to the tripod head, which 
is a desirable characteristic. All the other features remain the same 
as in the Y-level construction. 

This instrument, which is almost exclusively used in Europe, has 
not yet met with that favor by American engineers, which its simplicity 
and accuracy so justly deserves. This is due partly to its greater 
inconvenience in adjusting as compared with the Y-level, and partly 
on account of defective construction, inferior telescope and other 
neglected details, which usually obtain in instruments of this kind. 

We are confident that a dumpy level possessing a good telescope, 
sensitive bubble and stability, will do just as good work as the more 
costly Y-level. While the adjustment of the latter is made more 
readily, the former will retain it longer. 

( )ur dumpy level has a bronze center, a 16-inch telescope, and a 
vial of such curvature, as to give for each inch of motion of the bubble 
an angle of three minutes. 

There is no clamp or tangent screw to this form unless ordered 
by the customer. 

The bar, telescope and vial case are "Torchon" finished, and the 
latter may be provided with a folding mirror, which acts as an important 
protection to the more exposed spirit level when shut down, or as 
an indicator to the observer at the eye-piece, of the exact position of 
the bubble, when elevated. See No. 20M, Page 101. 

The stadia hairs may also be supplied to the dumpy level. 

Other Levels on Sale. 

In addition to the high grade instruments described, we also keep 
on hand a supply of smaller and less costly goods for leveling. With 
these instruments work may be done by the ditcher, irrigator, con- 
tractor, grader, farmer, dike-builder, gardener, plumber, architect, 
forester and military man, sufficiently precise for many ordinary pur- 
poses, wherein great accuracy is not required.

REMARKS 

In the foregoing we have endeavored to give the reader a fair 
idea of the principal engineering instruments made by this firm. We 
desire to convince our future customers — our old patrons we have long 
since convinced — that we are building conscientiously upon scientific 
principles, that every part and detail has been carefully studied to 
meet the requirements of our engineering fraternity, of the climate, 
and of all those conditions that influence the shape and character of 
every feature of the surveying instrument. It must permit of all 
operations at the least expenditure o"f time, it must be compact, it 
must be light, it must be absolutely accurate, it must be rigid, it must 
be stable and it must possess strength. And wherever a possible im- 
provement is suggested in any detail, it must be applied at once and 
tested as to its probable merits, and if it prove of value, no time must 
be lost in introducing it. These are the principles that have governed 
the manufacture of the articles which we have brought to your notice. 

New improvements have always had our attention, without any 
regard of the expenses incurred in experimenting. We need only 
refer to the introduction of aluminum in the manufacture of survey- 
ing instruments, which, we are fully convinced, has been crowned with 
success, to prove to our patrons that we never allow any conservative 
notion to rule the establishment. The particulars of this new field of 
manufacture will be found in another chapter of this part of the 
Manual. 

With the object constantly in view to make only the very best 
article that can be produced, and ever ready to introduce improve- 
ments and to experiment with suggestions that may lead to 
them, our instruments are held at a price that is commensurate with 
their qualities. Their values are rated by those current among first- 
class instrument makers ; they are no more, but they are no less. We 
do not handle cheap goods, and the trade that we are most anxious 
to please is that willing to pay a fair price for a number-one article. 

It was our purpose to describe in this catalogue only the instru- 
ments for which there exists the greatest demand, and for this reason 
we do not intend, at this time, to enter into any detail of the manu- 
facture of other scientific apparatus that we are in position to furnish 
upon due notice. 

Theodolites of the highest grade for the most exact purpose, 
reading with micrometers to the most refined division, are made

upon order to any desired shape and design, and with every required 
accessor)'. 

We also manufacture the topographer's plane-table, either in its 
simplest form, as recently perfected by the highest authorities, or in 
its most delicate arrangement of parts, as devised for work of the 
greatest precision capable of being put on paper. A number of plane- 
tables made for our institutions of learning, and for surveying depart- 
ments of the I'. S. Government, have given absolute satisfaction. 

The modern improved plane-table alidade is a particular specialty, 
to which we have given considerable time and attention. This instru- 
ment has been constructed by us of aluminum, which has been a per- 
fect success, proven by the fact that many have been almost daily 
in use for many years, under very trying conditions, without giving 
rise to the first complaint. Under the head of Aluminum for Sur- 
veying Instruments, this will be again referred to. By a combination 
of aluminum and aluminum bronze, the center of gravity of the 
alidade may be brought close to the foot of the standard, which is a 
very essential point in its construction. 

ALUMINUM FOR SURVEYING INSTRUMENTS 

A great deal has been said and written about this comparatively 
new metal of late, so that its characteristics have become generally 
known. 

Its color is a dull white, similar to silver, and rather pleasing to the 
eye. It embodies many qualities that make it a very valuable material 
in the mechanic arts. It is quite soft, but possesses malleability, 
tenacity and ductility, so that it may be made into very thin sheets, 
or drawn out into fine wire. It is a conductor of heat and electricity. 
One of its principal features is that it does not oxydize in the atmos- 
phere, and that it does not lose its brightness under conditions that 
would tarnish silver and blacken it, for sulphuretted hydrogen or sul- 
phide of ammonium do not influence its color. But the greatest ad- 
vantage is its remarkable light weight, the specific gravity being only 
2.6, or one-fourth of that of silver, and for this particular quality its 
use has been sought in the manufacture of articles requiring small 
weight, ever since the cost of its production has justified it. 

One of the many alloys is the so-called aluminum bronze, which 
unites hardness with malleability, and is therefore extensively used 
for many purposes. This alloy, however, gains little in lightness 
as compared with the ordinary metals.

Since it has been the constant aim to produce field instruments 
that shall combine strength with the least practical weight, there could 
not have been found a better application for aluminum than in the 
instrument-maker's art. 

It was necessary to experiment with it in different directions, 
particularly as to the proper alloy — it being much too soft in its pure 
state — that shall give the required tensile strength and stiffness, make 
it workable without fretting, and yet add little to its weight. An alloy 
is now made that fully satisfies these conditions. 

One of the principal objections urged against it in the manufacture 
of surveying instruments is, that on account of extreme lightness they 
would not be steady enough in the wind. This firm has built over 
iooo transits and levels of aluminum, and, in our opinion, they are 
quite as rigid as any other, if properly constructed, care being taken 
to adhere to the old material in such details where it cannot be dis- 
pensed with. We have found that the stability of an instrument 
depends more particularly upon the construction of its lower parts. 
If the combination of base-plate and leveling apparatus be made so 
that the instrument can be rigidly held, the center of gravity may be 
brought down lower, and that in itself would tend to increase its 
stability. 

Aluminum transits are made by the A. Lietz Company in three 
sizes, being complete field instruments with every accessory. The 
large transit weighs 10 pounds, and the smaller one A]A pounds, which 
reduces the weight by 40%. The construction is precisely the same as 
in the instruments already described. 

The base-plate is of composition metal, the inner center of the 
hardest bell metal, and the outer center of bronze. The leveling screws 
are also of composition, as well as the telescope axis. 

These transits may either be left in the beautiful natural color of 
the metal, or other shades may be applied. The standards are 
"Torchon" finished. 

The Licts Telescopic Solar Attachment is now made of aluminum, 
which can only be an improvement in any direction, whether its weight 
be added to the top of a transit made of the red metal, or to one of 
the new metal. Lightness in the solar attachment is a very desirable 
feature, and that may be easily obtained now. 

In the Y-level the base-plate and leveling screws and center are 
of composition metal ; the collars, the hardest bell metal ; and the rest, 
aluminum. It has an 18-inch telescope, its weight being 6 l / 2 pounds.

SAN FRANCISCO, U. S. A. 

We also manufacture a plane-table alidade of aluminum, with a 
ruler of aluminum bronze. This instrument, although of the same 
weight as one of the ordinary metal of the same size, possesses the 
particular advantage of having its center of gravity as low as it can 
possibly be brought to the table, and that when placed upon the board 
it will be absolutely stable, and will not be influenced by the wind, 
which causes the ordinary alidade to tremble and travel on the paper. 

And this is the reason why we should object very strongly to an 
aluminum rule in a plane-table alidade. This part of the alidade 
should be of heavy material, as well as the lower part of the standard, 
while the rest may be constructed as lightly as possible. In this case 
little or nothing may be gained in the weight, but very much is gained 
in stability, when compared with an instrument made of one metal 
throughout. Under no condition should the rule, which is the base 
of the structure, be made of a light material. 

Twenty-six years of experience in the construction of aluminum 
surveying instruments finds us ready to advocate the judicious use of 
this material. We have applied it in transits and levels, and have 
accomplished a saving in weight of about 40 per cent. Great care is 
exercised in the proper distribution of the metal. We have already 
stated that in a transit aluminum is never used in the construction of 
the base-plate, centers, leveling screws, telescope axes and all minor 
parts having threads. The principal horizontal members, the plates, 
are of aluminum, strongly ribbed. 

Much has been written about its high coefficient of expansion, 
and particular stress has been laid upon the effect of unequal expansion 
necessarily induced by the use of different metals. If this matter be 
considered for one moment, however, it will soon be seen that practi- 
cally there can be no serious result from this source. In the first 
place, the difference between the coefficients of brass and aluminum 
is altogether too small* that the effect of any possible distortion in 
material judiciously placed need necessarily be feared. Glass plays 
a very important part in the make-up of a transit. The coefficient of 
expansion in glass is very low (0.8 mm. per meter, raised 100° C) 
and a metal best adapted for our purpose would be one having the 
same coefficient. Now, as far as brass and aluminum are concerned, 
it is readily seen that there is practically no difference in them when 
compared with glass. As long as glass is used, one may as well 
employ aluminum as brass for the constructive parts, for while the 

* Physical laboratories have established the following: For brass 1.88 mm. per meter of 
length, raised in temperature 100° C; for aluminum 2.34. Our deductions are made from these 
data. 

Page 39

expansion of the latter exceeds that of glass 0.000072 inches per linear 
foot for i° Fahrenheit, that of the former does so only by 0.000103. 
Unequal expansion, therefore, is not a source of error that need 
reasonably be feared. 

The more vital objection to a light instrument — its greater un- 
steadiness in the wind when compared with a heavier make — is some- 
thing we have already referred to. We have made and sold over 1000 
aluminum transits and levels, and every one has been a proof of our 
statement made twenty years ago : that the stability depends more 
upon the construction of its base and connection with the tripod than 
it does upon the weight of what may be called its superstructure — 
the part above the leveling head. 

It may also be mentioned incidentally that a fall will injure an 
aluminum instrument less than if made of red metal. Not only is this 
theoretically correct, but our actual experience in this line has proven 
to us the fact that from ordinary accidents the lighter instruments 
are always less seriously injured than the heavier ones. 

The testimonials from our customers will show the public that the 
aluminum instruments made by our firm have given the fullest satis- 
faction, and have not disappointed our expectations. 

We are firmly convinced of the adaptability of aluminum for sur- 
veying instruments, and for that reason our firm has gone extensively 
into that branch of manufacture, for which every facility has been 
added' recently to the capacities of the shop. The aluminum instru- 
ment is forty per cent, lighter than the other, is just as strong, is just 
as precise in its workings, possesses every requisite detail of a com- 
plete field instrument, and, we claim, is just as stable. Those of the 
engineering fraternity who have to carry the transit all day, the mining 
and railway men, who climb the mountain sides during the long sum- 
mer days from early until dark, will not be long in finding out these 
advantages and in putting them to a severe test in every direction. 
After manufacturing aluminum instruments for twenty-six years we 
have had no occasion to regret it, and find constant encouragement 
from the best professional men. 

CARE OF INSTRUMENTS 

The greatest source of danger to a delicate instrument is careless 
handling. It is often subjected to violent usages for which there is 
absolutely no need. The rude way of manipulating its delicate parts; 
the unnecessary display of digital strength in operating a clamp; the 
useless strain applied to the leveling screws; the careless manner of 

Page 40 



f&fl&^hf THE A. LIETZ COMPANY 

SAN FRANCISCO, U. S. A. 

carrying it; the rough method of taking; it out of its case, or replacing 
it : and the incautious closing of a lid or door of a box by force, before 
the instrument is somewhat adjusted to its position ; all these are 
sources of danger that vitiate its adjustments and cause no end of 
trouble and expense. Although a well-made instrument is so designed 
as to stand many a shock without direct injury, any daily repeated 
abuse is sure to have its ill effect, from which your work must suffer. 

As the usefulness of a transit or level may be preserved for many 
years by a little attention to details, we shall enumerate a few of the 
principal points which the engineer will do well to observe. 

Always protect your instrument from rain by throwing over it 
a waterproof bag; and if it gets wet at all, clean it thoroughly after 
getting under shelter. It is not well to enter a hot room from the 
cold air, without giving it some protection. The condensing vapor 
settling on the metal and glasses is certain to give rise to injuries. 
It is always safe to place the instrument in its case before going into 
a warm room in winter. It is not well to leave your transit or level 
exposed for hours to the hot sun. Shade must be given either by a 
hood thrown over the instrument, or by an umbrella. 

But accidents are liable to happen, and for that reason we have 
noted down a few remedies in case of an emergency. 

The general tendency in the use of the screws is to overstrain 
them. This should never be done, especially with the cross-wire 
screws, which, when brought up too tight, are liable to constant change 
and loss of adjustment. The leveling and clamp screws, if over- 
strained, wear out sooner and may show fretting. If this takes place, 
they should be taken out and brushed with a little coal oil or benzine. 
The nuts are best cleaned by screwing a flat piece of soft wood through 
their apertures. In putting them together oil them slightly. 

Fretting of the centers and of the telescope-slide will interfere 
more with a correct working of the instrument than any other part out 
of order. They should be watched, therefore, very closely, and as soon 
as any rough motion manifests itself, it should be remedied at once, 
if possible, by an instrument maker. If this cannot be had, and the 
fretting is in the slide, first scrape and then burnish down the place 
where it frets. It may also be ground slightly with oil and very fine 
pumice stone dust, which is best obtained by rubbing two pieces on 
each other. After grinding then a little, the tubes should be cleaned 
and placed together again with oil only; then move them in and out 
a number of times, wipe the oil off, and finally put them together 

Page 41 



THE A. LIETZ COMPANY g?^o R ¥S 1 i£Mg 

SAN FRANCISCO, U. S. A. 

when dry. Should the fretting occur in the centers (if properly made 
and constructed, so that they do not come apart in detaching the 
instrument from the tripod, this will never happen), employ the same 
means; and if this be not effective, place a washer, made of paper or 
a thin card, between the shoulders. This will cause a shake, making 
accuracy impossible, and will introduce errors of parallax in reading 
off, which is better, however, than to destroy the centers wholly. The 
best unguent for them is very fine watch oil. Regarding our centers, 
we are fully prepared to assure our customers that no fretting will 
ever happen, as they are never exposed, and made with the utmost 
care. 

The object-slide should not be oiled. Never, under any condition, 
use emery in trying to repair an instrument, as it cannot be removed 
again and will grind continually. 

An efficient lubricant for leveling screws, clamps, pinions, etc., is 
well-rendered marrow. 

If an instrument is upset, thereby bending centers and plates, 
do not turn it unnecessarily, as this will disfigure the graduation, but 
send it to a competent instrument maker immediately. There should 
be no delay in repairing defects. 

In the matter of the tripod, it is wise to look to the screws that 
hold the legs frequently, and to keep them well tightened up ; and to 
inspect the shoes, to see that they do not come loose. An instrument 
cannot be steady if there is any shake in the tripod, which is its sup- 
port and must be firm in every particular. 

The graduation is a very delicate detail to handle, and should be 
approached only with the utmost care. It is safe to leave this part- 
to the instrument maker, and not to attempt to remove the plates, as 
they cannot be properly recentered without the aid of a testing 
apparatus. An exposed graduation may be cleaned with a little watch 
oil and a chamois skin, taking care not to touch the edges while this 
is done. 

To preserve the sensitiveness of the needle, the center pin must 
be prevented from becoming dull. The instrument should never be 
lifted without raising and arresting the needle, and if, upon letting 
it down again, the swing is too large, gently stop it when within a 
few degrees of its natural bearing. Every check and start must be 
made gently, never abruptly. Should the point become dull, it is best 
to send it to an instrument maker ; if this be not practicable, a watch- 
maker may perhaps attend to it. It should be remembered, however, 

Page 42 



SURVEYORS' lXSTKI M I IE A. LIETZ COMPANY 

SAN FRANCISCO, U. S. A. 

that the point of poise must be centered — that is, occupy the center of 
the graduated circle. This cannot be done by a watchmaker, and is 
only to be relied upon if made in an instrument maker's shop. 

If a needle is made of good steel, well hardened and properly 
charged, it will not often lose its magnetism; and if, when placed 
away, it is always brought to line in the meridian, it will retain, or 
even increase is polarity. If a needle has lost its magnetism it may 
be charged again with an ordinary horseshoe magnet ; one of three 
inches in length will be suitable for this purpose. The operation is 
this : hold the magnet with the poles upward, then, with a gentle pres- 
sure, pass each pole of the needle from center to extremity over the 
opposite pole of the magnet, describing before each pass a circle with 
a diameter of about double the length of the needle, taking care not 
to return it in a path near the pole. If the magnet is strong enough, 
the needle need not be taken out at all, but by raising it against the 
glass and then passing the magnet over this, it will be charged suffi- 
ciently. After charging, the needle has lost its balance, which may 
be easily restored by shifting the balance wire on the south end. 

The observer should always satisfy himself that there be nothing 
about his clothing, especially in the make of the buttons, that would 
have any influence upon the needle. 

In the matter of the telescope, intelligent handling will do much 
towards preserving its accuracy and reliability for a long time. In 
cleaning any of the lenses, use a soft rag or chamois leather. If the 
glasses should become greasy, or very dirty, wash them with alcohol. 
The inner faces will seldom require cleaning, and it is not advisable 
to take the telescope apart too often, as it is likely to destroy 
its adjustment. If dust should settle on the cross-hairs, it is safest 
not to touch them. The only remedy that may be tried is to take out 
both the object-glass and the eye-piece, and to blow gently through the 
tube. This may remove the dust without injuring the threads, but it is 
quite a delicate operation. 

Cross-hairs may be replaced in the field by the engineer. The 
spider web is cleansed from dirt by placing it in water for a few 
minutes. A little manipulation readily removes any particle that may 
adhere to the thread. After drying for a moment, adjust it to the 
diaphragm, previously cleaned from dust, and attach it by means of 
a little shellac. It requires considerable practice to do this nicely, 
for a spider's web, although quite strong, cannot be handled by clumsy 
fingers without parting; but in the case of an emergency the engineer 
must try to do the best under all circumstances.

Referring again to the lenses, it is well to remember that in taking 
them apart, the centering is disturbed, and the engineer is not able to 
replace them properly, especially if they fit loosely in the cell, which 
is very often the case. The staining of flint-glass lenses is caused by 
the corrosion of the oxide of lead contained in the glass. This will 
generally occur when the lens is kept in a damp place for some time. 
In cleaning an object-glass, care should be taken not to rub it any 
more than necessary. Brush off the dust first with a camel-hair brush, 
and then wipe it carefully with a clean piece of chamois leather. If 
very dirty, wash it with alcohol or water and soft chalk, being careful 
to have the latter free from grit. 

Considering that, in cleaning, each rub will destroy more or less 
of the fine finish of the lens, upon which depends the brightness and 
brilliancy of the image, the surveyor will be well repaid for his care 
in this particular. 

Similar attention must be bestowed upon the eye-piece. With our 
high power eye-pieces, a motion of only three-sixteenths of an inch is 
necessary to allow for difference in eyes. As the sliding motion is for 
this purpose alone, it is not at all necessary to disturb it after it has 
once been properly adjusted, as long as the same person is using the 
instrument; even in packing it away in the case the eye-piece may be 
left so, as this extra extension is allowed for in the box. The cap is 
provided with a slide to protect the eye-lens from dust while the 
instrument is not in use ; the engineer should never neglect to close 
this, and to cover the object-glass with its cap as well, as soon as 
the instrument is set at rest. 

Repairs.* 

We are fully prepared to make careful repairs to all instruments, 
from the graduation of an arc or circle, and the straightening of a 
center or plate, to the setting of a simple screw. In this particular 
branch we have operated here for the last thirty-odd years, and have 
gained the fullest confidence of our people. We need only state here 
that we guarantee satisfaction to our customers in every way. 

As we are located in California, separated by the breadth of the 
continent from our Eastern colleagues, we are necessarily required to 
repair instruments of almost every known make, and this has com- 
pelled us to procure the various requisites in the workshop for all 

* Experience has taught us that it is not wise to allow an ordinary mechanic to attempt 
instrumental repairs, as frequently resorted to in inland towns. It is always the case that 
this proves ruinous to the instrument, and subsequent repairs will be more extensive and 
expensive than if it had been shipped to the instrument-maker at once. Express charges 
are of far less importance, and may be made very reasonable. See notice in front of 
this manual.

emergencies. Today we are in the position to renew any part of an 
instrument, no matter where it was originally manufactured. Time and 
money will be saved by sending directly to us, and we shall try to give 
our customers every satisfaction. Whatever is entrusted to us will 
be thoroughly overhauled and put in the best possible condition, unless 
specified orders are received to confine the repairs to certain details. 
As a general thing it ought to be left to our judgment as to what the 
instrument requires ; it may cost a little more if you follow our advice 
in this particular, but it will certainly be more satisfactory in the end. 
It will save time, trouble and additional expense. In the course of our 
examination of an instrument needing repairs, we discover defects that 
could not be apparent to any one before its parts were separated and 
individually tested. What may appear of no consequence, and is there- 
fore neglected, is quite likely to lead to all sorts of subsequent inaccu- 
racies in your work. Years of experience in this particular line have 
taught us the advisability of urging this point upon our patrons. 

Considerable correspondence is had from inquiries about the cost 
of repairs. Although it is impossible to state the exact figures before 
an examination, there are certain rates for ordinary repairing that we 
may mention here. 

The most expensive instrument in this regard is the transit, being 
the most complicated in parts. If injured by a fall, new centers and 
a new telescope axis is generally required, the cost varying from $10 
to $50, reaching, sometimes, much higher. If slightly injured it will 
vary from $5 to $15. 

Injuries sustained by leveling instruments are generally less 
serious. A new level vial costs from $2 to $7.50, according to size 
and sensitiveness. Instruments defective in construction or workman- 
ship will not require a sensitive level, as that would be a source of 
constant annoyance to the engineer ; the bubble should be chosen to 
harmonize with the general qualities. As a rule, we attach to the 
better class of instrument a level that shall give for each inch of motion 
of the bubble an angle of two minutes ; to the inferior grade, one of 
three or four minutes. 

Compasses sent to us are generally injured by the dulling of the 
center pin. Sometimes the plates and sights are bent and the glass 
broken. Often the center cap is worn out, and a new one is required. 
The cost of repairing ranges from $2 to $8, and even as high as $10. 
A new needle, having the largest breadth in a vertical direction, which

is far superior to the flat style, costs $5. A new center pin, 75 cents. 
New center cap with jewel, $1.50. 

Careful readjustments made under the collimators are charged 
for at the rate of $2.50 for each instrument. 

Transits and levels should always be accompanied by the leveling 
plates ; the tripod and head need not be sent. With compasses the 
ball spindle should be sent. 

We advise our customers to pack their instruments carefully, when 
sending them to us for repairs, as they are liable to material injury 
if this precaution be neglected. The space in the box between the 
different parts — of the transit particularly — may be filled with soft 
paper wads to protect it from jars and blows. It is well to put the 
case in an additional box, a little larger in dimensions, in such a man- 
ner that the top of the case is plainly visible and its leather strap handy 
for carrying. The space between the case and the box may be padded 
with shavings, or some •30ft material to take up the shocks. Mark upon 
the top of the box in large legible letters :

The name of the sender and his address, together with the value of the 
instrument, should also appear on the box. 

This will insure comparative safety in transportation, which is a 
point that should be well observed by the engineer. And this precau- 
tion would also increase the responsibiliy of the carrier, in case the 
instrument had suffered during transportation. 

When an instrument is sent to us for repairs, a letter or postal 
card should be mailed at the same time, to inform us of the fact, 
giving the necessary directions, and stating when the return is required. 
The receipt of the instrument will be acknowledged by us at once. 

Kindly address all correspondence to salesroom, 61 Post Street.

SURVEYORS' INSTRUMENTS 



ADJUSTMENTS 

Adjusting an instrument consists in delicately moving to the right 
or left, and up or down, certain parts that must be either parallel or 
at right-angles to each other. This is done by slightly turning a num- 
ber of capstan-headed screws or nuts by means of a small steel rod, 
called an adjusting pin. Adjusting the vernier and compass consists 
in placing certain points in a straight line ; but as these corrections are 
always made by the instrument maker, they do not properly apply to 
the subject before us. Verniers, limb and needle, if properly placed 
at the outstart, will not need any correction in the ordinary use. 

Of the Transit. 

i. Adjustment for Parallax. — This is a very essential one, 
and must be looked to carefully in every surveying instrument, whether 
transit, level or theodolite. It consists in so focusing the eye-piece 
that the cross-hairs shall stand out distinctly and well-defined, when 
the telescope is directed upon an object in focus. If this is not properly 
done the hairs will be dim; they will appear to travel and to seem 
unsteady when set on a mark. We know that this has given consid- 
erable vexation to the observer, and instruments have been disparag- 
ingly condemned for their apparent parallax, when nothing more was 
necessary than a slight movement of the eye-tube to focus the hairs 
properly. This fact should be well borne in mind. Our eye-pieces are 
quite easily moved in or out by a revolving motion, which affords a 
very fine and precise adjustment to focus. 

Operation. — Direct the telescope so as to have a clear view of the 
sky, and then turn the eye-tube by the cap as just described, until the 
cross-hairs stand out like two sharp and distinctly drawn black lines. 
After a few trials this is accomplished without difficulty. Then try 
the telescope upon some object brought into focus and test the clear- 
ness of the wires. A point now bisected must stay so while the eye 
is moved laterally in front of the eye-hole. If it remains stationary, 
there is no parallax and the adjustment is made. Once properly set, 
the eye-piece may remain for the same observer for all time, and need 
not be adjusted from day to day. Attention has already been called 
to this point in a previous chapter, where it was noted that the instru- 
ment box was made large enough to allow the eye-piece to extend 
beyond the tube. (The sun-shade should be put on the telescope first, 
and then focused to mean distance to balance it properly.) 

2. Plate Levels. — The object is to set the levels at right-angles 

Page 47 



TTJT? A T TFT7 PAA^D 4 MV MODERN ENGINEERS' AND 
Ifllj -TV. J-/JU-J 1 Li Kj\j£t\.r j\.XS\ SURVEYORS 1 INSTRUMENTS 

SAN FRANCISCO, U. S. A. 

to the vertical axis of the instrument, so that when the bubbles are 
centered the axis is truly vertical. 

Operation. — Bring the bubbles to the middle of the tube by means 
of the leveling screws, then turn the instrument on its center 180 
degrees. If they remain central for any position, they are in adjust- 
ment ; if not, they must be elevated or depressed at one end to correct 
them. One-half of the required correction is made with the capstan- 
headed screws on the vial case, the rest by the leveling screws of the 
instrument. Several repetitions of the operation may be required be- 
fore attaining accuracy. It is well to have the plate in such a position, 
that the levels shall be parallel to a pair of opposing foot screws. If 
they are out considerably, it is better to adjust one first, approxi- 
mately, and then the other. 

3. The Standard Bearings. — The telescope should revolve in 
a vertical plane when the instrument is level. One end of the tele- 
scope axis must be either raised or lowered until accuracy is reached. 
A capstan-headed screw is attached for that purpose. 

Operation. — Set the instrument up within about fifty feet of the 
wall of a house. Take a well-defined point as high up as possible on 
the wall ; clamp and bisect ; then turn down the telescope and put a point 
in line as low on the wall as may be conveniently reached. Reverse 
the telescope and direct again to the upper mark, if you please ; clamp 
and bisect ; turn down to the lower mark, and if it is bisected, the 
telescope revolves in a vertical plane and requires no adjustment. If 
it does not strike the point absolutely, one-half of the difference is 
taken up by the capstan-headed screw, and the adjustment is done. 
Several repetitions of the operation may be required. It is not neces- 
sary to level the instrument, but it should be brought in such a position 
as to admit the bisecting of two well-defined points. Care should be 
taken, however, that the observation is made at the intersection of the 
cross-wires, and that the instrument is securely clamped. 

This adjustment should always be made before that of the cross- 
wires, for this reason : that unless points of equal height are taken 
in the subsequent adjustment of the vertical hair, it will only then prove 
correct, if the telescope revolves in a truly vertical plane. It is, there- 
fore, always better to look to this before the cross-hairs are adjusted. 

This adjustment may also be made by means of an accurate strid- 
ing level, such as manufactured by this Company for use in high-grade 
instruments. The transit must be precisely leveled up by the foot- 
screws and plate bubbles, after which the striding level is placed across 

Page 48

SAN FRANCISCO, U. S. A. 

the telescope, resting upon its axis. It is evident that the bubble will 
indicate any deficiency in the horizontal parallelism of this axis, and, 
therefore, any error in the true vertical motion of the telescope, which 
may be corrected until the bubble of the striding level remains centered. 

4. The Cross-wires. — The line of collimation should be at right- 
angles to the axis upon which the telescope revolves. 

Assuming that all the required conditions have been fulfilled by 
the instrument maker — having placed the telescope in the center of the 
instrument, and having the tubes perfectly straight and normal to the 
telescope axis, which are necessary instrumental requirements, there 
are two methods that may be employed. One is by means of back and 
fore-sights, which is that generally used ; the other consists of a test 
by means of three points in a range, where the middle one is occupied. 
Preceding either method the hair should be made truly vertical, so 
that either the upper or lower end will bisect a point when the tele- 
scope is moved up and down. This is easily done by loosening the 
diaphragm and turning it slightly in the required direction. To accom- 
plish this the instrument must be leveled up. 

Operation, First Method. — Occupying a point, direct the telescope 
to some well-defined mark, about four hundred or five hundred feet 
distant ; clamp and bisect it ; then revolve the telescope and place a 
point in the opposite direction at about the same distance. Now un- 
clamp and turn the instrument half-way around ; set the hair again on 
the first point, revolve the telescope and sight to the second point. 
If the intersection bisects the latter, the vertical hair is in adjustment. 
If not, the error can be corrected by the capstan-headed screws, which 
afford a lateral motion of the diaphragm. With them the vertical 
thread should be moved one-fourth of the space intercepted between 
the direction of the telescope and the direction of the second point. 
Several repetitions may be necessary to obtain accuracy. 

The reason why only one-fourth of the space should be corrected 
for, becomes evident from the fact that in the first revolution of the 
telescope the error of the hair is doubled ; and after reversing the 
instrument and revolving the second time, it is again doubled, but on 
the opposite side, so that the true direction lies exactly half way be- 
tween the two, and to correct for it we must move the hair one-half 
the space between the true line and one of the points. 

It is not necessary to level the instrument in order to make this 
adjustment ; but in case it is not leveled up, the observations must be 
made exactly at the intersection of the cross-wires. 

Page 49 



THE A. LIETZ COMPANY * 



SURVEYORS' INSTRUMENTS 



SAN FRANCISCO, U. S. A. 



It must be remembered that the image at the cross-hairs is in- 
verted, and that in consequence the screws must be moved in appar- 
ently wrong directions. 

If there is any lost motion in the tangent screw, great care should 
be exercised in handling the telescope, so as not to influence its align- 
ment. 

Operation, Second Method. — Locate with the telescope three 
points in one direction, which are necessarily in a straight line, as long 
as the vertical movement of the telescope is in adjustment. Occupy 
the middle point with precision, and bisect one of the end points ; 
revolve the telescope and sight at the other end point. If this is bi- 
sected, the instrument is in adjustment ; if not, correct for it by taking 
up one-half the error. This method requires leveling of the instru- 
ment. 

Thus far we have been speaking of the vertical hair only, as it is 
the more important in a transit telescope. In a plain transit — that is, 
one without a telescope level and without a vertical arc — the horizontal 
thread simply serves to define the middle of the vertical one, so that 
the observation may always be confined to a particular point in the 
latter. But if a level is attached to the telescope, then the horizontal 
hair should be brought into the optical axis, before the level is set 
parallel to the line of collimation; otherwise, though adjusted for long 
distances, it will fail to be correct for short sights. 

Operation. — Set up the instrument near a house or fence and level 
up carefully. Clamp the telescope, and by means of its tangent screw 
bisect a point several hundred feet distant; then turn on center and 
mark a point on the house or fence, about ten feet distant. Now un- 
clamp telescope, reverse it, revolve on center, and again bisect the near- 
est point. Turn instrument on center and see whether the hair inter- 
sects the further point. If it does not, the correction must be made, 
by lifting or lowering the diaphragm by means of the upper and 
lower capstan-headed screws, until the bisections, after repeated trials, 
will coincide. 

5. The Telescope Level. — The object of this adjustment is to 
make the level parallel with the line of collimation. The principle 
underlying the method is : that points taken with the same angle of 
elevation or depression, and equally distant from the instrument, are 
of equal height. 

Operation. — Set up on a nearly flat surface and level carefully. 
On opposite sides, at equal distances, drive two stakes giving the same 

Page SO 



^^£^1^;^ THE A. LIETZ COMPANY 

SAN FRANCISCO, U. S. A. 

level-rod reading, with the telescope bubble centered in each instance. 
These points are necessarily on a level with each other. Now move the 
instrument to a point in line with both, and about ten feet distant from 
one. Level up again. Take a rod reading on the nearer and then on 
the further stake. If they agree, the level is in adjustment; if not, 
move the telescope with its tangent screw over nearly the whole error, 
and sight again at the nearer stake and then at the further, repeating 
this until the readings are the same on both, when the telescope is truly 
horizontal. Now bring the bubble in the center of the tube by the 
correcting screws of the level, and the adjustment is completed. 

This adjustment may also be made in a room with the aid of a 
surveyor's level, with absolute accuracy. 

Operation. — A few feet (one or more) from each other set up 
the transit and level, each directed to the other. The cross-hairs of 
the level must be illuminated by a light, so that they shall become 
plainly and clearly visible through the transit. For this purpose cover 
the eye-end of the level with a bit of white paper and place a lamp 
behind it. Focusing both instruments properly will make the hairs 
appear very distinctly. Now, if both instruments are properly colli- 
mated, the level carefully leveled up, and the transit telescope of such 
height that we may view the interior of the level's tube, we are ready 
to adjust the transit telescope to a level plane, which is done by simply 
placing the intersection of its cross-hairs delicately over the intersec- 
tion of the level's cross-hairs. All that is required after that, is to 
center the transit's level bubble by means of the proper adjusting 
screws. 

This method recommends itself on account of its extreme sim- 
plicity. 

6. Zero of Vertical Arc. — This adjustment, once made by the 
instrument maker, is seldom vitiated. The object is to have the zero 
line of the circle agree with the zero mark of its vernier, when the 
level of the telescope indicates a horizontal position, and when the 
centers of the instrument are truly vertical. 

Operation. — The instrument must be carefully leveled by the 
small plate bubbles, and then the telescope by means of its level. This 
accurately accomplished, the vernier is shifted until the zero lines 
coincide. This must be carefully done, so that the instrument is not 
disturbed, and, when the vernier is fastened, care must be taken to 
allow a space that shall neither be too small nor too great between it 
and the vertical circle. In the first case it would bind under certain 

Page 51

SAN FRANCISCO, U. S. A. 

conditions of temperature, and in the latter the observer would not be 
able to obtain an accurate reading. The coincidence of the zero-lines 
must be made with a magnifying glass, and all parallax avoided. 

7. Centering the Field of View. — On some transit telescopes 
there will be found another set of four capstan-headed screws, exactly 
alike to that which regulates the cross-hair diaphragm, and placed in 
a position quite close to it. These screws are for the purpose of direct- 
ing the tube of the eye-piece in such a manner that the field of view 
may be divided by the cross-wires into four uniform quadrants; that 
is, they enable the operator to so adjust his field that it may be bisected 
horizontally and vertically by the threads. In the Lietz transits this 
adjustment has been omitted, for the reason that the tubes are made 
of such length and with such care — being absolutely straight — that 
there is no need of displacing the field, after the line of collimation 
has been made to agree with the optical center, and the hairs are 
properly adjusted. The lines can never appear noticeably out of the 
field in our transits, and any additional movement in the parts of the 
telescope would neither be useful nor desirable. A first-class transit 
instrument can dispense with this arrangement altogether, and for 
this reason it is not usually found there. With an extra long telescope, 
however, there would be a slight advantage in being able to direct the 
field of view, for a possible fall of the instrument may so injure the 
tube that it could not be made absolutely straight again afterwards, 
and in consideration of this, we have adopted this correction only in 
the case of the 18-inch Y-level, which is the most liable to be damaged 
in that way. It alone possesses two sets of capstan-headed screws near 
the eye-end of the telescope — one for the adjustment of the cross-hairs, 
and the other for shifting the field of view so that it shall appear equally 
divided by them. 

Of the Y-Level. 

There are three principal adjustments. The spirit level must be 
parallel to the axis of collimation ; it must be at right-angles to the 
vertical axis of the instrument; the axis of collimation must agree 
with the optical axis. 

There are other instrumental requirements which belong to the 
instrument maker, however, and it is with the above three adjustments 
only that the surveyor has to deal, as they are likely to become dis- 
turbed in time. 

Before examining the adjustments, the sun-shade should be placed 
on the telescope, as it is only accurately in balance with this. 

Page 52

SAN FRANCISCO, U. S. A. 

1ST Adjustment. — To set the spirit level parallel to the line of 
collimation, and, at the same time, place its axis in a plane with that 
of the telescope. It is best to attend to the latter first. 

Operation. — Turn the telescope so as to stand over two opposing 
foot-screws, clamp the instrument and bring the bubble to the center 
of the tube ; then rotate the telescope in its Ys, so as to put the level 
considerably out of a vertical — say about 15 or 20 degrees. If the 
bubble changes its position, it shows that the axis is not in a plane 
with that of the telescope. Correct it by moving the two side screws 
of the level case, until one-half of the deviation has been taken up. 
A few repetitions will insure accuracy, and destroy the side motion 
of the level. 

The level must now be made parallel with the line of the bottom 
of the collars. 

Operation. — Bring the bubble to the center of the tube; then 
reverse the telescope in the Ys end for end ; do this carefully. The 
displacement of the bubble, if there be any, is the double error, which 
is corrected by taking up one-half of it by means of the adjusting nuts 
on the level case, and the other half with the leveling screws of the 
instrument. This operation is repeated until the bubble remains in the 
center. 

To accomplish a proper adjustment of the level to the line of colli- 
mation, it becomes absolutely necessary that the collars be of equal 
diameter. We have already referred to the importance of even collar 
dimensions, and have laid great weight upon this requisite; and here 
again we shall point out the errors to which a neglect therein may lead. 
A Y-level in such an event is not any better than a dumpy, and will 
have to be adjusted as such. 

Providing the Ys are filed out to the same absolute angle, the 
instrument may still be adjustable in all its parts : — the spirit level may 
be made parallel to the line of the bottom of the collars ; the Ys may 
be so adjusted that the bubble will remain in the center of the tube; 
the line of collimation may be brought to the center of revolution of 
the telescope ; and this reversed end for end in the Ys, leaving the 
bubble in the middle, even if there be some difference in the diameter 
of the collars. It is the general opinion that after level, Ys and cross- 
wires are adjusted, the instrument must be correct. This is by no 
means certain, as the least difference in the size of the collars will 
throw out the line of collimation considerably. This difference is some- 
times found in new instruments, and is also produced by unequal wear, 

Page S3

SURVEYORS' INSTRUMENTS 



SAN FRANCISCO, U. S. A. 



denting, etc. It is therefore advisable that the equality of the collars 
should be tested from time to time, which is done by a method given 
further on. 

2D Adjustment. — To piace the level at right-angles to the vertical 
axis of the instrument. 

Operation. — Turn the instrument so that the telescope shall stand 
over the line of two opposing leveling screws, and bring the bubble 
to the center of the tube; then turn the instrument 180 degrees on its 
center. If the bubble shows any displacement, correct one-half of it 
by means of the nuts under the bar at the Y supports, and one-half by 
the foot-screws. Several trials will make the correction perfect. 

3D Adjustment. — To place the cross-web in the optical axis of 
the telescope, so that the intersection will remain on an object in 
revolving it. 

Operation. — Set the intersection of the hairs on a point about two 
hundred or three hundred feet distant, then revolve the telescope in 
its Ys half-way, so as to have the level case on top. If the wires have 
moved from the point, bring them back one-half of the amount of the 
displacement. Try again, and repeat the operation if necessary. 

The eye-piece may then be properly aligned and directed by the 
four black capstan-headed screws (nearest the eye-end of the tele- 
scope), so that the field of view shall appear evenly divided by the 
cross-hairs, as already explained. 

In this, as well as in any other telescope, we assume that the tubes 
are straight, the object-glass well centered, and the slide well fitted. 
If such be not the case, the telescope can only be adjusted for certain 
distances. It is urged by some makers that it is almost impossible 
to produce straight tubes, and that, therefore, the object-slide must 
be adjustable. This, however, is entirely erroneous. Perfectly straight 
tubes can be made, if the necessary time and money be expended, which 
is the only requisite. In a great many instruments sold today, you will 
find that the object-glass is not centered, that the slide is poorly fitted, 
and that all these inaccuracies, which are not apparent at a glance, 
prove more injurious than ever if the tubes are not quite straight. It 
must also seem clear to any one that the constant working of the slide 
in an adjustable ring would loosen the screws and cause considerable 
annoyance. 

Parallax is adjusted by moving the eye-piece in or out until a 
clear and distinct view of the cross-hairs is obtained, as in the case of 
the transit already described. 

Page 54 



ffi THE A. LIETZ COMPANY 

SAN FRANCISCO, U.S.A. 

The Collar Tkst. — After the instrument is properly adjusted, 
the equality of the collars may be ascertained in the following- manner: 

Operation. — Make two bench-marks, place the instrument exactly 
midway between them, and find their true difference of level by reading 
leveling rods set upon them. Now place the instrument near one of 
the bench-marks and read the rods again. If the difference of the 
reading is equal to the true difference of level, the collars are of equal 
diameter, and the line of collimation is at right-angles to the vertical 
axis of the instrument. This test, once made, holds good ever after, 
as it shows that the collars are true, and consequently that a correct 
adjustment is assured of all its other parts, as already described. But 
it need hardly be mentioned that denting, the settling of sand particles 
and unequal wear will also affect the adjustment in the same manner. 

If the test shows that the line of collimation is not perpendicular 
to the line of the vertical center, then the collars are of unequal diame- 
ter, and the instrument is really nothing more or less than a dumpy 
level, as this defect deprives it of all the advantages for an easy and 
convenient adjustment, which characterizes the Y-level in comparison 
with the dumpy. 

This defect may, however, be temporarily remedied or adjusted 
in the same manner as the line of collimation in the dumpy level is 
adjusted, but it must ever thereafter remain permanently in its Ys, 
as it would, if reversed end for end, double the error which existed 
previous to this adjustment. 

The correction may also be made by displacing the horizontal 
cross-hair to the extent that the line of collimation shall be truly hori- 
zontal and, at the same time, parallel with the axis of the spirit .level ; 
but, in that event, there will be no longer any agreement with the optical 
axis, which again gives rise to a number of inaccuracies that cannot 
be obviated. 

A Y-level, in order to deserve that name at all, must have equal 
diameters of its collars ; and if that is not found after a crucial test, 
the instrument maker should be called upon to remedy this dis- 
crepancy. 

No doubt can possibly exist in the mind of any engineer of the 
absolute necessity of the collar test. Considering the required parallel- 
ism of the axis of collimation and the axis of the spirit level, he must 
know that a contact can only be made between telescope and Ys by 
means of the collars, whose exteriors may either be parts of the surface 
of a cylinder, or that of a cone, and that the required parallelism is

only possible in the former case. If one collar exceed the other in 
diameter, the centered level bubble, if reversed in the Ys, will indicate 
a displacement corresponding to four times the angle intercepted be- 
tween the collar axis and that of the spirit level. No further demon- 
stration of this fact is necessary. 

Of the Dumpy Level. 

In principle, the same laws govern the requirements of the dumpy 
that hold good in .the Y-level. Although its construction differs, the 
condition of its line of collimation, optical center and level vial must 
be such as to bear that universal relation to each other which we have 
fully explained in the other instruments. It is not difficult to make 
all the necessary adjustments properly, although it may not appear 
quite so handy to correct its errors as in the case of the Y-level. 
Once adjusted, however, the instrument will remain so for a long time, 
and it will give the operator considerable satisfaction, if used with the 
ordinary care. 

The adjustments of the level, and the telescope for collimation, 
will now be briefly mentioned. 

Put on the sun-shade, and focus the eye-piece until the hairs are 
distinctly visible and the parallax destroyed ; then proceed as follows : 

Operation. — Turn the instrument so that the telescope shall stand 
directly over the line of two opposing leveling screws, and draw the 
bubble to the middle of the tube by means of the foot-screws. Then 
turn the instrument on its center 180 degrees, and if the bubble remain 
centered the adjustment is perfect. Any displacement, however, will 
have to be corrected by taking up one-half of it with the capstan-headed 
screws attached to the level case, and the other half by the foot-screws. 
This operation must be repeated several times, in directions normal to 
each other — that is, over one set of opposing foot-screws as well as 
over the other, until the telescope may be swung in any position and 
the bubble will remain in the middle. See that the adjusting screws 
of the level vial are firm, yet avoid all unnecessary force in tightening 
them; all cramming is injurious, and tends to destroy the proper 
degree of refinement required. 

After having set the diaphragm so that the cross-hairs shall be 
absolutely horizontal and vertical, which is easily done by loosening 
the capstan-headed screws and turning the diaphragm slightly, being 
guided by some point bisected by the horizontal hair, we now proceed 
to adjust the cross-hair, which must be brought into the collimation 
line. Several methods are known ; the one which is always available, 

Page 56 



gS^.S^ K^ TH E A. LIETZ COMPANY 

SAN FRANCISCO, U. s. A 

however, is that by means of stakes and level-readings upon them, and 
it is to this that we shall confine ourselves here. 

Operation. — Choose a piece of ground nearly level, set up the 
instrument and center the bubble. Drive a stake (point i) firmly, say 
two hundred or three hundred feet from the instrument, in any con- 
venient direction therefrom. Hold the level rod upon it and take a 
reading. Now point the telescope in the opposite direction, the bubble 
being centered, and plant another stake (point 2) at the same distance 
from the dumpy, driving it until the rod shall read the same as upon 
the first point. These two stakes are on the same level. Now set up 
the instrument abount ten or fifteen feet from the first stake, and bring 
the bubble to the center; take a rod-reading on point 1, and then on 
point 2. If the two readings are alike, with a truly centered bubble, 
the hair is collimated. If there is any difference, take up nearly ah 
of it by moving the diaphragm with the cross-hairs either up or down, 
as already explained. Repeat this operation until the readings on 
points 1 and 2 are identical, when the instrument is in adjustment. 

The vertical hair is of no particular importance. 

With these precautions, a dumpy level may be made absolutely 
accurate, and there is no reason why, for any of the land surveyors, 
and for nearly all of the engineer's work, this compact and steady 
instrument should not meet every requirement. We frequently discuss 
its merits with our customers, and have never hesitated to recommend it. 

Test of Telescopes in General. 

If a telescope is to be tested for its qualities, make sure that all its 
lenses are perfectly clean. 

To test for definition, use small, clear print, and view it from a 
distance of from thirty to fifty feet. If the print appears clear and 
well defined, and fully as legible at this distance as if viewed with the 
naked eye at the distance of distinct vision, the surfaces of the object- 
glass are perfect and well finished. If, on the contrary, the print ap- 
pears dull and indistinct, and the finer details illegible, or even invisible, 
the surfaces are imperfect and faulty, for the rays proceeding from 
the various points of the object are not refracted to their correspond- 
ing points in the image. 

Indistinctness may be caused by spherical aberration. 

To test this, cover the object-glass with a ring of black paper, 
reducing the aperture to one-half ; again focus small print to distinct 
vision; remove the ring of black paper and cover the center of the 
object-glass (previously left open), then mark how much the object- 

Page 57 



THE A. LIETZ COMPANY ^^o^Sf^ 

SAN FRANCISCO, U. S. A. 

glass has to be moved in or out for distinct vision. If the spherical 
aberration has been reduced to a minimum, very little, if any, slide mo- 
tion is necessary to obtain a distinct view under both tests. The amount 
of movement, however, constitutes a measure for the spherical aberra- 
tion of the object-glass. 

Another test, but not as good as the one just mentioned, is to focus 
an object to distinct vision ; then slide the object-glass in or out, observ- 
ing at the same time the quantity of motion necessary to render the object 
indistinct. If the spherical aberration is completely corrected, the object 
should, theoretically, be rendered indistinct by the slightest motion of 
the lens ; but, practically, this is not the case, as the eye will accommodate 
itself in a measure to the difference of divergence of the rays, caused 
by the motion, in or out, of the object-glass, in. the same manner as it 
will accommodate itself to near and distant objects when viewing with- 
out the aid of lenses. So, if the image formed by a perfect object-glass 
is viewed by another perfect lens of long focal length, say six inches, 
the object-glass might be moved in or out one-fourth of an inch from 
the point of distinct vision, and the object will still appear compara- 
tively clear, as the one-fourth-inch motion, with an eye-lens of such 
long focal length, cannot cause enough difference in the divergence of 
the rays to prevent the accommodation of most eyes to it. The shorter 
the focal length of the eye-lens, the more rapid will be the change of 
divergence or convergence of the rays with a certain amount of motion ; 
therefore, the second test is only applicable with eye-pieces of very 
high power, which, at the slightest motion in or out, will cause a 
sufficient amount of divergence of the rays to prevent the accommoda- 
tion of the eye to the change. 

To test the chromatic aberration, either a celestial body or a white 
disc should be selected for an object. 

Focus the object to distinct vision, thereupon move the object-glass 
slowly in and out alternately. If, in the first instance, a light yellow 
ring is seen at the edge of the object, and in the second one a ring of 
purple light, the object-glass may be considered perfect, as it proves 
that the most intense colors of the prismatic spectrum (orange and 
blue) are corrected. 

To test the flatness of field, take a square, flat object, the sides of 
which are about four inches long and perfectly straight — the best object 
is a heavily-lined square, drawn on white paper with india ink. Sight 
this object from such a distance that it will nearly fill the field of view 
of the telescope, and see if it still appears flat and its sides perfectly 

Page 58 



ISgl¥^K?'?^5K;H^ THE A. LIETZ COMPANY 

SAN FRANCISCO, U. S. A. 

straight; if so, the telescope is a good one. If, on the contrary, the 
object appears distorted, I. c, if the sides, instead of being straight, 
form curves and the surfaces appear concave, instead of flat, the tele- 
scope is not good, for it shows that the proportions of foci, aperture 
and distances between the different lenses are not according to the laws 
of optics ; owing, generally, to the attempt to force the magnifying 
power beyond its limits. 

As all the refractions of light in the telescope are caused by flat 
and spherical surfaces, it is evident that the edge of a round flat object, 
when used for the above test, cannot be distorted, but that the surface 
only will appear concave to a keen observing eye. A telescope which 
distorts the image to a perceptible degree will not, however, cause any 
errors in common use, if only one point in the lens is taken in all ob- 
servations, but it is decidedly objectionable in stadia measurements, 
where two points in the field of view are used at the same time. 

To Find the Magnifying Power of a Telescope. 

A practical method for finding the magnifying power, available to 
anyone, which does not require any apparatus, taking up only a few 
moments' time, is the following: 

Set up the instrument, and about twenty or thirty feet therefrom 
hold up a graduated rod. Observe the rod with one eye by direct 
vision, and with the other through the telescope. Assume a certain 
space on the rod, say the height of a numeral, or two sharply drawn 
lines, and count the number of divisions on the rod in that space ; then 
observe the number of divisions that are seen by the naked eye in the 
same space enlarged. The ratio between the two is the power sought. 
It is the reading of a magnified space of known length on the graduated 
face of the rod. With a little practice both eyes will be able to distin- 
guish the rod divisions at the same time. If what is known to be o.i 
of a foot, is enlarged by viewing it through a telescope so as to cover 
the space of 2.4 feet as seen by the unaided eye, the magnifying power 
is 24 for the distance in focus. The real power is somewhat less, for 
as the tube of the telescope is drawn out for near objects, the power 
necessarily increases. The magnifying power obtained by this method 
holds good for the distance that the rod can be read by the unaided 
eye, and it is always somewhat greater than the actual power. 

For a very accurate determination of the magnifying power, it is 
necessary to ascertain the focal length of the objective and that of the 
eye-piece, in order to compare them and to find their proportion. While 
the former is easily obtained by a direct measurement from the objective 

Page 59 



THE A. LIETZ COMPANY ¥8$^o® ( i®®g$ a ®& 

SAN FRANCISCO, U. S. A. 

lens to the cross-hairs, the latter, usually containing an entire system 
of lenses, presents numerous difficulties. For this purpose we possess 
an apparatus especially designed for us. 

Dividing the focal length of the objective (when the telescope is 
focused to mean distance) in millimeters, by the equivalent gives the 
magnifying power of the telescope under consideration. 

If any of our customers want the focal length of an eye-piece deter- 
mined, we shall cheerfully do so, without charge, upon receipt of it, 
which should be sent carefully packed. 

Adjustments of the Plane-Table Alidade. 

Without going again into all the details of instrumental adjust- 
ments, it behooves us to enumerate the points required of this instru- 
ment when in proper condition. These are: 

1st — That the fiducial edge of the rule be absolutely straight; 

2d — That all parallax be destroyed, by placing the cross-hairs in 
proper focus ; 

3d — That the line of collimation move in a vertical plane ; 

4th — That this plane be normal to the plane of the ruler ; 

5th — That the same plane also intersect the fiducial edge of the 
ruler, or at least be parallel thereto ; 

6th — That during parallelism of the optical axis and the fiducial 
edge, the zeros of the vertical arc and its vernier correspond. 

This instrument is used in the topographical departments of the 
U. S. Coast and Geodetic Survey, and the U. S. Geological Survey, and 
is exclusively applied in mapping the topographical features of the 
country in Europe, usually by officers of the army, who control these 
surveys, after the triangulation points have been established. 

This method of surveying has been constantly improved in prac- 
tice, particularly by the experts of the Geological Survey, and it may 
be safely said that, with the required accuracy, nothing surpasses it for 
small-scaled work in speed and application. All the bulky parts of the 
table have been reduced to a minimum, so that it may be handled with 
comparative ease in the roughest mountain country. 

We refer our readers to appendix No. 22 of the Coast Survey 
Report of 1865, which may be had separately in bound book form, called 
The Plane-Table and its Uses, as an excellent theoretical and practical 
treatise of this interesting subject. Price $2.00.

INTRODUCTION 

The following illustrations show the principal articles we manu- 
facture, being, in the case of this section, almost exclusively confined 
to instruments required by the civil, mining, irrigation, hydraulic and 
military engineer, for making accurate measurements and surveys for 
any purpose whatever. 

Of the surveying instruments each illustration, or plate, is com- 
plete within itself. Every feature is carefully noted, together with the 
price and a general description in a condensed form. The additional 
accessories that may be had in each instance are also enumerated and 
their prices given. It is well, however, that the engineer should con- 
sult the preceding part of this Manual, wherein every detail is care- 
fully described and extensively discussed. If pains are taken to look 
this over, the reader will obtain such information as would be given 
him in the salesroom. 

Every article has been numbered, and by these numbers our cus- 
tomers may order, without going into a minute description of the 
articles wanted. For example : 

"Send me transit No. 4 (1919), with the following extras " 

is all that is required to designate to us exactly what is desired by our 
patron. 

In ordering please mention the issue of the catalogue, as the num- 
bers of preceding issues necessarily conflict. 

See also Telegraph Code on pages 66 and 67. 

With the detailed information on its succeeding page, every plate 
becomes a complete price list of the particular instrument illustrated. 
Every effort has been made to make this part of the book as intellig- 

Page 64

ible a- possible, without the necessity of searching over numerous 
pages to gather information. 

Although we shall make any instrument of precision called for, 
we desire to state clearly that we have made a particular specialty of 
engineers' and surveyors' instruments, because there is for them alone 
a demand at the present time, and for this reason our shop facilities 
have been especially designed and improved for the manufacture of 
these articles. 

If instruments for a more scientific purpose are wanted, for astro- 
nomical or geodetic work, for instance, we can either make them on a 
special order, or we can import them for our customer, having made 
arrangements in Europe which enable us to sell such instruments as 
cheaply as anyone in the United States. For institutions of learning 
we import without payment of duty. 

All our products have been priced commensurate with their quality 
and deductions are not made from our price list, which agrees favor- 
ably in all its quotations with those of the best Eastern firms. 

^'e furnish a first-class article at a fair price, and our goods 
stand upon their individual merit. It has been our object to create the 
best that the instrument maker's art can make or devise, and with the 
records of the past decades before us we feel that we have been suc- 
cessful in every way.

THE LIETZ TRANSIT THEODOLITES 

WITH UNITED STANDARDS, "PATENTED" 

Your attention is called to the additional features incorporated in this

plate and "U" shaped standards, so constructed as to permit of a larger cir- 
cular compass.

^^■^^.k^ THE A. LIETZ COMPANY 

SAN FRANCISCO, U. S. A. 



THE LIETZ PATENT UNIFIER 

The "Unifier" is a rigid rod looped in the center to clear the line 
of sight, connecting both standards firmly, thereby securing lateral 
rigidity and avoiding stress in a degree heretofore unknown. (See cut 
with telescope removed.) 

The telescope revolves around the "Unifier," and its pivots are 
cylindrical, resting in "V" shaped bearings which secure the refine- 
ment of motion in a vertical plane necessary for precise work. 

Its characteristics insure the greatest stability and permanency of 
adjustments with less liability of injury. All the adjustments, as well 
as the manipulations, are the same as in other instruments. 

This transit has been given practical field tests for several years, 
which justifies its recommendation as a very superior article. 

This type of instrument was used with marked success and high 
satisfaction on the work of the Hetch Hetchy undertaking in Califor- 
nia ; also by the Marin Municipal Water District on the tunnel through 
Mt. Tamalpais, California. Too much cannot be said of the service- 
ability of this type of construction in instruments.

Instruments of very superior construction and design. The standards upon which the tele- 
scope rests and the upper plate are cast in one U-shaped piece, thus affording far more strength 
than the ordinary form. 

The telescope is reversible in position, as well as exchangeable in its bearings, which are pro- 
vided with dust caps and screws, to give them the proper friction. The telescope is either erect 
or inverting. For reasons already set forth (see page 24) the inverting form should be given 
the preference. The telescope possesses the finest lenses and optical accessories. It has a slide 
protector and is provided with a sun shade. The cross hairs are focused by a screw motion of the

LIETZ MOUNTAIN AND MINING TRANSITS 
"ALUMINUM" 

The illustrations on pages 84 and 88 represent our Mountain and 
Mining Transits Nos. 9 and 12. While with the introduction of our 
special aluminum alloy we have been the producers of the lightest in- 
struments for years, yet some of our patrons have expressed a desire 
to possess an instrument of smaller size, admitting of easier transpor- 
tation in mountainous country. These transits are made with as much 
care as our larger instruments ; the constructive details are similar, 
and full reliance may be placed upon the instruments as to the per- 
formance of their working parts in every respect. We would espe- 
cially recommend our friends to order these instruments in our special 
aluminum alloy, which not only makes them lighter, but adds consider- 
ably to the rigidity, lateral strength, and to their steadiness. This 
statement is made and based upon our experience gained in over 
twenty years, during which time we have manufactured more than 
one thousand instruments of our special aluminum alloy, and it is veri- 
fied by authorities who constantly use them. At first thought the state- 
ment may seem paradoxical that an instrument made of lighter mate- 
rial should be steadier than one made of heavier metals, and we are 
constantly confronted with queries from engineers, when we recom- 
mend instruments of the lighter type, whether these will prove steady 
enough in the wind. It seems that the ordinary opinion is not based 
upon practical experience but created by the reasonable assumption 
that heavier weight will offer more resistance to disturbing influences 
than light weight. 

While it cannot be denied that the weight of an instrument adds 
to its steadiness, it must be borne in mind that instruments have not 
been made of the older metals in order to gain steadiness, but simply 
because this was the best material available for the purpose. Wear and 
resistance in case of accident were the principal features sought. A 
light material, provided it has these qualities, offers the best oppor- 
tunity to produce the most rigid instrument, for the reason that it ad- 
mits of lowering the center of gravity by a judicious distribution of 
the metals, and this is what we have aimed at and believe we have 
fully accomplished in our aluminum alloy instruments. These instru- 
ments are rigid and firm ; they offer more resistance in case of a fall 
than the heavier metals ; the wearing qualities are such that no bush- 
ing is required ; the coefficient of expansion and contraction is elim- 
inated, so that their adjustments will remain constant under severe 
conditions. Their qualities during the last twenty years have been so 
thoroughly tested that we conscientiously recommend them to the 
profession. 

It must be apparent that there cannot be any great difference in 
price between a large and a small sized instrument. The workmanship 
in each is alike, and, if anything, more complicated and costly in the 

Page 36

LIETZ RECONNAISSANCE TRANSIT No. 12 
In Case 



smaller. The only difference is in the quantity of metal used, but, as 
this cannot possibly amount to much in price, it is more than compen- 
sated for by the additional care required in handling the smaller parts. 
This explanation would hardly seem necessary, were it not for the 
prevailing impression that all merchantable articles of the same kind 
shall be rated by their respective sizes. That this cannot obtain in the 
case of instruments must stand to reason. The price of a transit can 
only be reduced by omitting certain features, or by changing it to a 
simpler construction.

LIETZ BUILDERS' LEVELS Nos. 21 to 21 BC 

As made by ns for the use of architects, builders, contractors, and for 
general engineering work not requiring the highest degree of accuracy, the 
instrument is constructed along the same lines as our No. 20 Precision 
Dumpy Level, and therefore not liable to get out of order, an important 
feature, because instruments of this kind occasionally have to be intrusted 
to men whose duties will not admit of the greatest amount of care. The 
instrument is far superior to the so-called architects' level, which is built on 
the principle t>f the Y-level, and in which novelties are usually embodied to 
attract the buyer and which tend to make instruments complicated and un- 
reliable, difficult to manipulate, and which usually decrease their strength 
considerably. Our instrument No. 21 is built for the special purpose of ob- 
taining the simplest form of an accurate and reliable tool and is offered to 
the profession as an instrument of efficiency at a very moderate price.

LIETZ PRELIMINARY TRANSIT No. 22 

For many purposes where great accuracy is not required, it is often 
far more convenient to use some small instrument which will admit of 
measurements within practical limits. The irrigator, farmer, ditcher, 
grader, building contractor, gardener, forester, road builder, etc., often 
require means of obtaining heights and relative positions, for which 
higher grade instruments would be unnecessarily refined. 

It is for such purposes that we have constructed the Lietz Pre- 
liminary Transit. This combines portability with accuracy and relia- 
bility, within a reasonable limit, at a minimum expenditure. In appear- 
ance it is identical to an engineer's transit. It possesses four leveling 
screws, but no shifting center. The lower axis moves in the star piece 
which carries the four leveling screws. It is readily clamped in any 
position by means of clamp and tangent screws. The second spindle 
carries the top plate, together with- the standards and telescope. The 
compass is centrally located, and has a diameter of three inches. The 
plate is graduated in the regular way, and this graduation is utilized 
for reading horizontal angles by means of a vernier to two minutes 
of arc. The vertical arc is graduated from degree to 100 degrees 
each way, reading to two minutes by a vernier which is clamped readily 
into any position on the telescope axis by a milled-head screw, so that 
the position of the arc, which is stationary on the standard, admits of 
reading any vertical angle, by means of repetition, if over 90. The 
telescope is six inches long, has erect lenses, magnifying eight diam- 
eters. The telescope possesses a level two and one-half inches in length, 
and a tangential movement, so that the instrument represents a com- 
plete transit of modern construction, having, of course, a limited de- 
gree of accuracy, but capable of carrying out preliminaries where high- 
grade instruments would otherwise have to be used. Every feature of 
the transit is represented here, and it admits of obtaining results ap- 
proaching those of the surveyor's transit and level. 

Crude instruments are placed on the market to supply the demand 
for a fairly reliable measuring tool of small cost. These are usually 
worthless, as they are made without any regard for the underlying 
principles that should govern the make of such an article. But with the 
Lietz Preliminary Instrument, for which patent has been granted, the 
object has been attained. Every part is carefully made and neatly fin- 
ished, and its cost is less in comparison than the inferior articles usually 
offered for sale in the market.

LIETZ PLANE TABLE OUTFITS 




The advantages of the Plane Table for topographic surveying and map- 
ping has brought this instrument into very popular favor, especially in our 
irrigation districts and oil fields. 

A planchette or drawing board is mounted upon a specially constructed 
tripod head. The Johnson Movement consists of a socket with a flange to 
which the board is fastened. This socket is engaged and held by three 
segments in a manner to admit of the orientation of the planchette and also 
the clamping of it by means of a large milled head screw. 

The Lietz Tangent Head Tripod (page 120) is an improved form. While 
it entails the additional investment it is self-evident that its nicety of adjust- 
ment and its control of the planchette is a labor-saving feature, it being con- 
structed with the clamp and tangent in azimuth and the three screws for 
leveling. 

We offer several forms or modifications of Alidades. 

Our No. 30 represents a type as made for many years to meet the needs 
of the topographer, whereas No. 31 exemplifies the very latest form as 
adopted by the United States Geological Survey. Its improvement consists, 
briefly, of the telescope revolving 180 degrees on its longitudinal axis, thus 
admitting of an easy adjustment and control of the line of collimation, and 
the graduating of the vertical arc on the periphery for convenience in reading 
the angles, and its manner of numbered graduations. With the index of the 
vernier at 30 instead of it can readily be understood that all the angles 
as read are positive, overcoming thereby almost all possibility of error in 
the notes. 

Our No. 32 is, again, a modification of our No. 31 and is after the model 
adopted by the Geological Department of the Stanford University. Its com- 
pactness and resultant portability brought us .to the conclusion that it would, 
likewise, be appreciated by the members of the profession. Today they are 
in use in many of our States and especially in the oil districts of Oklahoma 
and Texas as well as in California.

TRIPODS FOR LIETZ INSTRUMENTS 




Made of selected ash, straight grained and well seasoned. Withstand 
unusual use. 

Our extension tripods are very rigid and strong and move freely under 
all conditions of heat and cold. The double clamps employed are of one- 
piece cast brass and will not break under ordinary use. We furnish many 
tripods equipped with one extension leg, which admits of all the advan- 
tages of the extension tripods as regard set-ups, their only disadvantage be- 
ing lack of portability. 

We call special attention, however, to the greater steadiness and free- 
dom from tremor in open windy country of our straight split-leg tripod 
No. 38 as furnished with our precision transits. In instruments of high 
power and sensitive levels it is the only tripod to be recommended. In use 
in cities and country it affords quick set-ups and easy carrying.

No. 110 



No. 110 Godwin's Improved Portable Heliograph. The improvement 
of the Godwin type lies principally in that it necessitates the 
need of but one tripod, whereas in most other forms two are 
necessary. 

Illustration "A" shows the outfit in use with the two mirrors, 
which are required in order to get the reflected sunlight if the 
sun is in the rear of the operator. Illustration "B" shows the 
outfit as it is mostly used when the sun can be reflected directly 
to the station to be signaled. 

Instrument consists of two mirrors, 3%x3% inches, adjust- 
able vertically and horizontally by micrometer movements, a 
shutter 4%x4% inches, a sighting rod, and one tripod 24 inches 
high. Instrument fits neatly in two chamois-lined trays, con- 
tained in leather case with shoulder strap. Weight of entire 
outfit 7 lbs. Price of outfit complete with instructions and code

The Aneroid, owing to its portable form and great sensitiveness in re- 
sponding to changes in pressure of the atmosphere (it will denote a change 
much quicker than the Mercurial Barometer), is today in more general use by 
observers of meteorological changes than any other form of Barometer. 

In measuring altitudes, owing to its portability, sensitiveness and the 
ease with which approximate results may be obtained, it is highly valuable 
to the Engineer and Surveyor, while the Tourist, with the Aneroid, notes 
his gain in elevation foot by foot, as well as plans his excursions in accord- 
ance with prognostications from its readings. 

The illustration shows the general 
construction of the movement with its 
elastic metallic box, called the vacuum 
chamber. 

This chamber is constructed with 
two circular discs of thin corrugated 
German silver, firmly soldered to- 
gether at the edges, forming a close 
box. The air is exhausted from this 
box which causes the top and bottom 
discs to close together. 

The vacuum chamber is firmly 
fixed to the circular metal base by a 
post upon its centre, projecting 
through the base plate. 

An iron bridge spans the chamber, 
resting upon the base plate by means 
of the two pointed screws. (These 
screws are used to finely regulate the 
tension upon the chamber.) 
To the bridge is fixed the mainspring, which is forced down by mechan- 
ical means sufficient to insert a knife edge piece. 

As this knife edge' is fastened (by means of a central pillar) to the top 
disc of the chamber the mainspring, when released, lifts the upper part of 
the chamber, drawing the two discs apart. 

As this forms a perfect balance (the power of the mainspring opposing 
the atmospheric pressure upon the vacuum chamber), any variation in air- 
pressure will now be shown by a movement up or down of the elastic 
chamber. A decrease in pressure will allow the mainspring to overcome 
the power of the vacuum, the action then being upwards, and an increase 
of air pressure will produce the contrary result.

times. To take reading insert measuring stick through the funnel into the 
receiver and note how high it is moistened. The sticks are graduated in lOths 
and lOOths of an inch, one inch of rain actually being 10 inches on the stick. 
To measure snow, remove the funnel and receiver and after collecting let it 
melt. Then pour into receiver and measure same as rain. Also measure 
full depth of snow.

The Self-Registering Rain Gauge has a receiver 8x8 inches. The rain enters 
this receiver and is collected in a bucket. When this bucket has received 
1 /100th of an inch of rain it tilts over, and the hand registers the fall as 
1 /100th of an inch. The tilting of one bucket brings another in position, which 
when filled overbalances, registers and brings the first bucket in position again. 
One complete revolution of the large hand indicates one inch of rain in 
l/100ths, and the smaller dial registers up to 10 inches.

LIETZ WATER REGISTERS 

As made by us for the U. S. Department of Agriculture 




Lietz Water 
Register No. 360 

(Galvanized Iron Cover 
not shown) 




The Lietz Water Register, for auto- 
matically recording the rise and fall 
of water in reservoirs, lakes, canals, 
weirs, etc., was originally designed 
and manufactured by us for the 
U. S. Department of Agriculture over 
twenty years ago, and has found wide 
application. Its simplicity of con- 
struction, together with efficiency and moderate price, has created its pop- 
ularity. We have made improvements from time to time, which have 
increased its efficiency, and the Register as made by us today constitutes 
the best moderate price device on the market. 

The customary ratios which we supply and aim to keep in stock are 
1:1, 1:2, 1:5, and 1:10, also a device whereby the pencil movement can be 
changed and made to travel over the drum in a period of either 1 or 8 days. 
(See Lietz Duplex Time Water Register Nos. 362-363.) Any other ratio, 
as well as interchangeable ratios, can also be supplied. 

The cut shows the latest improvements, which consist principally of a 
remodeled pencil carriage and a water-tight aluminum clock case; the entire 
apparatus is enclosed with a galvanized iron cover not shown in the cut. 

Write for folder containing Instructions for Installation, also abstract 
from paper published in Bulletin of American Society of Civil Engineers, 
November, 1910, by J. C. Stevens, describing results obtained.

THE A. LIETZ COMPANY 



SAN FRANCISCO. U. S. A. 



LIETZ WATER REGISTERS 

The Lietz Water Registers arc so constructed that the pencil is released 
by the clock and drawn across the drum by a small weight, which works 
in unison with the clockworks. The drum is controlled by the float which 
rests on the surface of the water. This type of construction is a great 
advantage over the old style, wherein the drum is revolved by the clock- 
work, inasmuch as it relieves the clockwork of the extra labor of turning 
the drum, thus assuring greater accuracy of time and also, in case of an 
extraordinary rise or fall of the water (greater than the capacity of the 
record sheet), the Lietz Water Register will simply make two or more 
revolutions and the record can easily be read, while on the old type of 
construction any rise or fall over the capacity of the Register would be 
lost. 

No. 360 Lietz Improved Water Register with 12-inch drum, high-

LIETZ DUPLEX TIME WATER REGISTERS 

The Lietz Duplex Time Water Registers 
are a modification of our Nos. 360-361 Water 
Registers. By means of attaching an extra 
gear and reel to the clockworks, the pencil 
can be made to travel across the drum in a 
period of either one or eight days. Either 
result may be obtained, as conditions neces- 
sitate, by winding the chain, which releases 
the pencil, on the proper reel.

^r<^P ^^^fl R^^. volves the cylinder "E," causing the 
( r f\ 1 1 mt FD 4k, ) ^^ supply roll of paper to travel over it 

( OUPJ i rr K , anc j onto (-jje record roller "G," which 

in turn is wound tightly through the 

fall of its counterweight. The paper is 

guided over the cylinder by means of 

small projecting pins or burs attached 

to its ends peripherally, which cause a 

perforation of the paper at intervals of 

one inch, equal to two hours of record. 

The scale on which the curve is drawn 

is such that one inch on the paper 

equals one foot in tidal height. 

The Reference Pencil "I," which may be shifted along its carriage, is a 

convenience in the establishment of either a mean or initial reading, which 

readily aids in the taking of observations. 

The gauge, once installed and in working order, need not be visited more 
than once in seven days for the purpose of winding the driving clock and 
the counterweight attached to the record roller. 

Price, complete with all accessories, including a galvanized iron hood 

(not shown in the illustration) and 6 rolls of record paper $150.00

HENSOLDT IMPROVED PRISM BINOCULARS 





Construction. 



No. 375 

Aluminum Frames, covered in black morocco* leather. Jointed cross 
bars for adjustment of pupillary distances. Universal focusing arrangement, 
and one turning eye-piece, graduated plus and minus, for unequal strength 
of eyes. Binoculars contained in genuine leather case with sling strap. 

The novel combined prism of the Hensoldt Binocular as shown in the- 
above illustration allows the employment of object glasses of larger aperture 
(up to 2 inches), thereby giving a higher degree of brightness than other 
glasses. It also permits the reduction of the Aluminum Frame to the 
slender shape of a telescope, as well as securing the optical elements more 
rigidly in proper relation to each other. 




This illustration shows the easy access to internal optical parts for cleaning. 
*On special order Hensoldt Prism Binoculars can be furnished in tan leather.

LEVELING RODS 

The Leveling Rods, Nos. 410-425, listed on page 181, are of our 
own manufacture, graduated to hundredths, by uniform, clean divi- 
sions. The black numerals, corresponding to the tenths, have an 
exact height of 0.06 foot and the red or foot numerals are 0.08 foot 
high. This affords a rod reading at distances where graduation lines 
disappear. The wood is the best, thoroughly seasoned. The target 
and all connecting metal parts are cast in one piece; the vernier 
made to read to thousandths ; the scale is brass, face of target 
japanned. We recommend these rods to be the best in the market. 
Made in two self-reading designs, known as the block and line 
graduations, similar to the Philadelphia pattern. 

We also manufacture a complete line of Flexible Leveling Rods 
and Stadia Rods as listed on the following pages.

ROD LEVEL 

No. 449 Lietz Improved Rod Level $3.00 

This Rod Level is an improved type, used to hold 
rod or pole of any shape perpendicular. The level 
bubbles are sunk in the casting at right angles to 
each other, thereby lessening the possibility of break- 
age, as well as making it easier for the rodman to 
hold the bubbles in the center than the old form of 
circular spirit levels. The latter are continually leak- 
ing and it is impossible to keep them in order. 

The Improved Rod Level can either be fastened 
to the rod by means of a flat-head screw, for which 
there is a key slot provided, or pressed against the 
rod or pole while holding. Indispensable for stadia 
work.

THE "CRIPPLE CREEK" REEL 





Aluminum frame 14 inches long; nickel-plated steel reel 
8 inches in diameter. A hardwood roller or spool is fitted 
between the sides or discs of reel which by means of a spring 
presses toward the axis of reel, causing the tape to wind up 
evenly and tightly and keeping it in place. Long, neat and 
strong aluminum winding handle with large metal finger hold, 
giving a winding leverage of nearly five inches, and enabling 
the winding of a long tape with exceptional ease and rapidity. 
A leather strap for carrying is attached to one end of the 
frame. 

The Cripple Creek Reel is the neatest, lightest, most con- 
venient, easiest working and most durable reel for long steel 
tapes made. Weight, A l / 2 lbs.

that it serves as a complete support in winding or unwinding 
the tape, and when the reel is not in use, the outfit can be 
conveniently carried over the shoulder. Weight, 2J4 lbs. 

This staff is very' strong, but light and very convenient.

POCKET MEASURING TAPES 

LUFKIN STEEL TAPES 
Standard of Measurements 

Lufkin Steel Tapes are so carefully graduated by Standards supplied by 
the United States Government that they can be used for testing the 
accuracy of other tapes. 

Tension: 

Lufkin Steel Tapes are made under a tension of 10 pounds for tapes up 
to 100 feet in length and 20 pounds if longer. They are accurate when 
supported full length at this tension. 

Temperature: 

Steel tapes graduated in customary English units (feet, inches, etc.) are 
standard at a temperature of 62° Fahrenheit. The National Bureau of 
Standards recommend tapes graduated in the Metric System be made 
Standard at 20° Centigrade, this being the normal temperature under which 
they are used. We are prepared to make them at 20° Centigrade if so 
desired, but unless otherwise specified, we will make them accurate at 
0° Centigrade, which is the customary Standard for Countries that have 
adopted the Metric System. 

CERTIFICATE OF COMPARISON 

OF THE NATIONAL BUREAU OF STANDARDS 

AT WASHINGTON, D. C. 

We can furnish a certificate of comparison of the National Bureau of 
Standards for any Lufkin Steel Tape the graduations of which are marked 
directly on the steel and the zero of the graduations is represented by a 
line marked on the tape. The fees of the Bureau of Standards for com- 
parisons are given below, to this must be added the transportation charges 
to and from Washington, D. C. 
(A) For total length, not greater than 100 feet or 50 meters, either 

supported throughout or at intervals $0.75 

For each additional 100-foot or 50-meter interval .50 

(D) For comparing total length both supported throughout and at 

intervals for length of 100 feet or 50 meters 1.25 , 

For each additional 100 feet or 50 meters 1.00 

(F) For each sub-division compared .10 

(G) For determination of length at an additional tension, for each 

100- foot or 50-meter interval .25 

(H) For determining the tension to the nearest 0.5 pound or 0.25 
kilogram at which the tape is most nearly correct at the 
standard temperature, for each 100-foot or 50-meter interval .50 

For tapes not sent on a reel there will be an additional charge 

for each 100-foot or 50-meter length or fraction thereof of .25 

The Bureau of Standards certificate states the temperature at which the comparison was 
made, the method of support, the tension used in making comparison, and the length corrected 
for the standard temperature. The number of each certificate is also etched on the tape. 

INSTANTANEOUS READINGS 



Instantaneous Readings, a patented system of marking steel and metallic tapes, consists 
of repeating the foot marks at every inch in small, yet easily distinguishable figures. Thus the 
total reading is brought directly before the eye, eliminating all chance of possible error, and 
saving valuable time.

DUPLICATING FIELD BOOKS 

The Duplicating Field Book fills a long felt want of civil and mining engineers where field 
parties are more or less distant from the office where the plotting is done. By making a single 
entry it enables the engineering corps in the field to furnish the home office with a duplicate 
sheet of their proceedings each day as the work progresses. 

The books are well bound in strong leather covers and contain 80 original and duplicate 
sheets and 8 sheets of special pencil carbon paper that will produce perfect and clean copies. 
The originals are of white linen ledger paper and are permanently bound. The duplicates are 
of strong yellow Manilla paper and are perforated and punched for filing in our Office Record 
Binder No. 786.

Loose Leaf Sheets 



Loose Leaf Field Books are advantageous to engineers in many respects. They enable one 
to leave finished notes in the drafting room while the books are still being used in the field 
and to remove certain leaves if necessary. We offer the profession the following assortment. 
Our Field Binders Nos. 790 and 792 are made of extra heavy leather covered material and are 
very durable. The mechanism is strong and consists of six metal rings which are readily 
opened when necessary. The Office Binder No. 791 is made of strong cloth covered material 
with similar mechanism. It is intended for use in the office and for filing sheets. This binder 
can also be used in the field and has proven very satisfactory for this purpose. The leaves are 
ruled on extra heavy stock and are similar in design and colors to our regular field books.

LOGARITHMIC PAPER 



Logarithmic Paper is so ruled that the scales in each direction are logarithmic instead of 
uniform, as on other cross-section papers; the numbers and divisions marked are placed at such 
points as to make their distances from the origin proportional to the logarithm of such numbers 
instead of to the numbers themselves. By means of this paper logarithmic operations are per- 
formed graphically, without reference to the logarithms themselves. Many hydraulic and other 
engineering computations are facilitated by its use, and various relationships (sizes of tie-bars, 
shafts, etc., in terms of varying load, or the inverse; circumferences and diameters of circles in 
terms of their radii or diameters, or the inverse; weights of the series of bodies of the same 
substance and form, but of varying size, or. the inverse, etc., etc.), can be represented.

The constantly increasing demand of the larger drawing rooms for standard sizes of 
tracing cloth and tracing paper sheets has induced us to cater to this requirement. We have 
executed any number of intricate jobs and our experiences are offered the profession with the 
assurance that highly satisfactory results will be had if this work is entrusted to us. Special 
non-smearing and absolutely opaque ink used. 

We call attention to the illustration above. Note that the printed headings are absolutely 
in line with the horizontal rulings, also that the lines are unbroken and joined perfectly, an 
accomplishment unattainable unless executed in our special manner. Sheets printed on the 
under or reverse side, if desired, to allow for thorough erasing or cleaning without danger of 
destroying the printed matter. 

Considering the time required for ruling borders and inserting corner titles and the 
saving of material, printed sheets are both efficient and economical. Let us quote you, regard- 
less of size, quantity or intricacy of composition.

VACUUM BLUE PRINT FRAMES 




No. 1275 

For obtaining the closest contact these frames are unsurpassed. By 
means of a pump the air is entirely exhausted from between the cushion and 
the glass, forming the best contact obtainable between the tracing and 
sensitized paper. 

By use of the vacuum frame the faintest lines of a drawing can be repro- 
duced, or drawings wrinkled or worn by much handling can be flattened 
out and good prints taken therefrom. 

This frame is particularly well adapted for making negative and blue 
line prints.

THE NEW BUCKEYE ELECTRIC BLUE PRINT 
MACHINE 




No. 
No 
No 



Of the various types of cylin- 
drical Blue Print Machines which 
have been offered we are convinced 
that the NEW BUCKEYE is the 
most practical from the standpoint 
of operation, the most economical 
from a viewpoint of operation cost 
and the most satisfactory from re- 
sults obtainable. 

An advantage of this machine is 
that it can be purchased with but one 
half-cylinder glass ; the other, to 
complete the machine, may be added 
later. This is an advantage where 
the first cost is a consideration. 

The half-cylinders are each pro- 
vided with a curtain to hold trac- 
ings and paper tightly against the 
glass during exposure, perfect con- 
tact being assured. Tension on the 
curtains is maintained by means of 
weights attached to small wire cables 
which engage both ends of the 
rollers. A roller being used on each 
side of the machine makes it possible 
to. operate one independent of the 
other, thus one side only may be 
used or one side may be unloaded or 
reloaded while the other is printing. 

LAMP — Especially constructed for 
blue printing, emitting an intense 
light, rich in actinic or violet rays. 

SPEED GOVERNOR, for regu- 
lating the length of exposure, is of 
the rotary type in an oil-tight case. 
The weight of the lamp supplies the 
power. 

SAFETY STOP— A device to pre- 
vent lamp from dropping in case 
supporting cable should break. 

AUTOMATIC CUT-OUT — Pro- 
vided to make it unnecessary for 
operator to continually watch ma- 
chine, the current being automatically 
shut off when lamp reaches bottom. 

When ordering ascertain from 
your electric company whether cur- 
rent is direct or alternating; if latter 
give frequency of cycles.

THE REVOLUTE BLUE PRINTING MACHINES 

The efficiency of the Revolute Blue Printing Machines is due to the fact 
that they are built upon the right principle, the principle of rolling 
(revolving) contact. 

Rolling contact is obtained by a revolving glass cylinder and a series of 
endless belts which move in the same direction at the same rate of speed 
and have perfect contact. 

The source of light passes through the glass cylinder and hits the tracing 
and paper which is fed between the cylinder and the endless belts and 
carried by them through the part revolution while the printing is being done. 

Rolling contact insures perfect and uniform contact between the tracing 
and the paper at all times which is essential in making prints perfect in 
detail and tone, and absolutely eliminates all tendency of the paper to slip 
on the tracing. 

The Revolute Blue Printing Machines will produce blue prints at the 
rate of two to twenty linear feet per minute, depending upon the quality of 
the paper and the tracing. The cost of operation per unit of output is 
extremely low and they are very economical to maintain and always ready 
for instant use, self-contained and compact. 

They will make a perfect reproduction of every tracing or negative 
regardless of its fineness of detail. They will print either separately cut 
sheets or continuous rolls from either cloth or paper tracings. 

They are devoid of complicated mechanism and are simply constructed 
and easily operated. 

On the Revolute Blue Printing Machines you will find every attachment 
that can be designed to aid their speed and efficiency. They are provided 
with variable speed gears with indicators which enables the operator to set 
the machine at the right speed for every variation in paper and tracings, 
insuring all prints perfect with no loss of time and material for tests. They 
are equipped with paper holders to which the paper may be attached and 
from which it will automatically feed into the machine. 

The very fast machines are, and the others may be, equipped with an 
automatic winding-up device which will rewind the paper as it is delivered 
printed from the machine. 

All machines are provided with automatic strippers which insure the 
paper and the tracing leaving the cylinder at the proper moment. 

If interested in Washing, Drying and Ironing Machines or other blue 
print room equipment send for descriptive circular.

PHOTO PRINT SERVICE 

Photostat reproductions of every description. Maps, blue prints, legal papers, financial 
statements, manifests and all written or printed documents can be quickly and economically 
copied by this process in any quantities. Prices vary according to size and quantities required 
and are cheerfully quoted on application. Samples of work sent on request. 

LITHO PRINT PROCESS 

A comparatively recent process by which tracings, either pencil or ink, can be printed 
upon tracing cloth, linaura cloth or papers of any desired thickness. It offers unlimited pos- 
sibles as can be appreciated from the fact that a tracing cloth copy can be made from a 
tracing, and from which in turn blue prints or negatives can be made if required. Architects 
find it most appropriate for duplicating their ink or pencil tracings upon heavier papers since 
rendering is beautifully effected in so doing. It being a DRY PROCESS all shrinkage is 
overcome. It can be appreciated that this is important in certain classes of work since the 
shrinkage in blue printing is well understood and under the negative and blue-line processes 
is doubled. 

Prices vary according to size and quantities, but compare very favorably with the charges 
as made for negative and blue-line work, and we therefore urge our friends to a consideration 
of the LITHO PROCESS when requiring copies of their tracings. Write us for quotations. 

MOUNTING SERVICE 

Patronage solicited for map mounting in all forms, continuous rolls, sheets, cut to fold 
for pocket use, etc. We have facilities for mounting extra large sheets, joining them per- 
fectly, and can furnish double mounted sheets (muslin between) for platbook or record use. 
Inquiries will receive prompt attention.

DRAWING INSTRUMENTS 

FACTS TO BE CONSIDERED IN SELECTING 

Before describing the qualities of the various grades of Drawing Instru- 
ments about to be presented, we feel that a few remarks on the selection 
of instruments are not amiss. This for the guidance of our friends residing 
away from the larger cities (where examination of the goods is impossible) 
and for the layman or student, inexperienced in the use of Drawing 
Instruments. 

We hope, by this, to. create a better understanding as to the different 
classes of instruments and their respective qualities and the purposes for 
which each line is primarily intended. 

The varieties and qualities of Drawing Instruments are now so numerous 
and the finish, in all, so very similar (even though the intrinsic values are 
far greater in one than in another), that we have found it difficult for most 
anyone to grasp the actual and the comparative values of an instrument. 

The quality can be determined only by their efficiency and durability 
in actual use and for this reason the advice of an instructor of drawing or 
that of an experienced draftsman is often sought by the beginner when 
considering the purchase of drawing tools. 

Few people, however, have the good fortune to be thus guided and are 
compelled to rely solely upon the reputation of the dealer. We solicit 
consultation, either by personal visit or through correspondence, giving the 
assurance to our patrons of an honest representation of the merits of the 
goods under consideration. The A. Lietz Co., with its long established 
business career and reputation for honest dealings, will positively insure 
against misrepresentation. 

The life and the efficiency of Drawing Instruments depends entirely 
upon the qualities of the materials or metals employed in their manufacture 
and not on the finish; upon careful and conscientious workmanship and on 
their design and general form. 

Drawing Instruments recognized as of the highest quality are made of 
finest hard rolled German silver and best English steel and are not cast or 
coined in die. The employment of hard rolled plate metal naturally adds 
to the cost of making but it is absolutely necessary in the production of 
durable instruments; and being so made, they will outlast the actual need of 
professional draftsmen; in fact, have been known to be in use through 
successive generations. 

DESCRIPTION OF VARIOUS QUALITIES 
Atee- SUPERIOR KERN SWISS DRAWING INSTRUMENTS 

By reason of the great care in the selection of the materials and the 
attention given to the perfection in all the details of their manufacture, 
Kern Swiss Drawing Instruments have during the last century become 
recognized as the world's standard and highest quality.

Each instrument stamped with trade mark. 




The Kern Patent Pivot Joint Head offers the great advantage over all 
other types of construction in that it entirely suppresses any lost motion or 
injurious friction and that the stability of the head of the compass is greatly 
increased. We carry all Kern Dividers and Compasses with straightening 
device which admits of maintaining the handle in a perpendicular position at 
all times. 




Original Pattern Compasses have the one leg made in 
one length. The needle is kept in a sheath and clamped by 
a set screw between the split end of that leg. Thus the 
needle may be put in any desired angle to it, i. e., perpen- 
dicular to the paper, permitting use of the entire length of 
leg and giving the compasses the widest possible range. 

The other leg taking the points is jointed instead of the 
needle pencil or pen pieces having their joint. 

The points are fastened in a very solid way and the 
needle in its holder or sheath is as steady as if in one piece 
with the leg.

THE RAPID DOT AND DASH DEVICE 




The Rapid Dot and Dash Device as applied to amber triangles or amber- 
lined T squares and straight edges is a simple and most practical one, con- 
sisting of an intermittent groove cut just in back of the edges. 

A small metal attachment, which can be adjusted to either nib of any 
ordinary ruling pen, travels along these grooves, the uncut portions causing 
the pen to be lifted off the paper, registering the spaces between the dots 
and dashes, while the cut portions form the dots and dashes. This attach- 
ment, when once adjusted, requires no changing and does not interfere with 
the use of the pen for straight-line work, nor do the grooves in any way 
affect the edges of the triangles or straightedges. 

We recommend this device as the most perfect and efficient dotting in- 
strument yet devised. The results obtained are absolutely perfect and the 
variety of designs is unlimited. We are in a position to furnish any special 
design to order and offer the following suggestions, which we can furnish 
on a day's notice:

ALCO "CIRCLE A" DRAWING INSTRUMENTS 

Each instrument stamped ftLCO ® 

The one point of great importance about ALCO "Circle A" Drawing 
Instruments is that they are all made to gauge, all parts being interchange- 
able. The materials used are very finest quality of rolled German silver and 
best steel. . 

COMPASSES AND DIVIDERS 

The foremost requirement in Compasses and Dividers intended for high- 
class work is an absolutely true and steady joint. By reason of their con- 
struction the joints of our ALCO "Circle A" Compasses can never become 
loose or work unevenly; it permits of exact adjustment and may readily be 
oiled. The construction is shown in the accompanying illustrations. Fig. 1 
shows the plain joint while Fig. 2 illustrates the joint in connection with our 
straightening device. 




Fig. 1 



Fig. 2 



Fig. 3 



The shanks of the Compasses which are centrically connected by a 
bipartite pivot showing a rounded head on either side, are enclosed by a 
fork carrying corresponding cavities on either side of its inner surface to 
receive the rounded heads of the pivots. The ends of the fork are drawn 
together by a screw passing between the legs of the compasses, by means of 
which the tension can be minutely regulated. 

The shanks of the compasses are thus held together, not by the natural 
and therefore transient elasticity of the fork, but by the permanent pressure 
exerted by the screw. This construction warrants a true and smooth action 
at all times. 

The straightening device forces the handle to remain in a central position 
to the legs. The construction will be clear by reference to Fig. 3.

The manner by which pen. pencil and needle point parts are held in place 
in their socket is very simple, but at the same time effective, so that these 
parts can never net shaky (See Fig. 41 The socket is split and the two sides 
being draw together by a T-bolt screw clamp the inserted parts firmly in 
place. 




Fig. 4 Fig. 5 



All Compasses are supplied with needle point parts; these when inserted 
turn the instruments into perfect Dividers. One of the legs is provided with 
a needle point held in a split reversible sleeve (Fig. 5), so that either a plain 
or shouldered point may be used. The points can always be adjusted to a 
position perpendicular to the paper regardless of the opening and without 
any noticeable shortening of the leg, in this way avoiding sliding and mis- 
placing of the center point and allowing the instrument to be used on a 
considerably larger radius than is possible with the old style Compasses, 
the lengthening bar being dispensable. 

All needle points have extremely fine and sharp points allowing of 
accurate spacing and leaving only the slightest marks on the paper. They 
are not ordinary sewing needles but are specially made for the instruments 
from best hardened steel. 

In all of the ALCO "Circle A" Drawing Instruments the steel points are 
removable. They are held in place by small clamp screws and can be 
exchanged very easily by giving the heads of the screws half a turn with 
the screwdriver. The troublesome regrinding of broken points is entirely 
done away with. If a point is worn or damaged it can be replaced by a 
new one. Reserve points are supplied with every set of instruments. 

The Compasses and Dividers are of the flat-half-round type. Corners and 
sharp edges are avoided as much as possible to make the handling more 
pleasant. Screws are placed between the legs so as not to obstruct the view 
when drawing.

ALCO "CIRCLE A" DRAWING INSTRUMENTS 

Each instrument stamped A LCO ® 

Another great advantage of the ALCO "Circle A" Drawing Instruments 
is the interchangeableness of all parts. Not only pen and pencil points of 
one pair of compasses will fit exactly into any other of the same size; the 
legs or any other parts of one instrument fit perfectly into any other, sizes, 
of course, being equal. 

With all Compasses ordered in cases a screwdriver serving as leadbox 
and a metal handle is furnished whose hollow space holds several reserve 
needle points. This handle serves for inserting pen, pencil or needle point 
part, so that each of them may be used as a separate instrument. 

SPRING BOW INSTRUMENTS 

Are made in two distinctly different styles: 

Style A. Instruments with ANNULAR spring, Fig. A (new style). 
Style B. Instruments with FLAT spring, Fig B (old style). 
We stock only the style A instruments. 




Fig. A 



Fig. B 



Both styles are fitted either with side or center screw adjustment. 

Bow instruments of the annular spring construction have the great ad- 
vantage that the tension of the shanks remains nearly constant for any spr'ead 
while Bows with flat springs (old style) become slacker the more they are 
opened. The shanks are made of German silver in this construction, whereby 
rusting is avoided. 

The threads of the adjusting screws are all cut very deep and coarse, 
especially those of the center adjustment Bows, to insure quick motion and 
to avoid the disagreeable stripping. 

All Steel Points Are Removable. 

All Bows have instruments comparatively wide spread, especially with 
the 4J4-in. Bows, so a good deal of work may be done for which the heavier 
Compasses usually are too clumsy.

Esch instrument stamped / mgo ® 

Bow Instrument No. 1665 is a very serviceable complete pocket set for 
small work. In connection with the metal handle it contains all the in- 
struments needed by a draughtsman for this kind of work. 



IMPROVED ROTATING BOW PENS 




All Rotating Compasses of the ordinary type have the disadvantage that 
the pen or pencil points move in an arc relative to the center point, and 
since a pen will draw properly only at one certain position to the paper, it 
follows that the angular changes occurring in the position of the pen point 
will necessarily mar the performance of the pen. 

In Rotating Compasses Nos. 1668 and 1669 the introduction of a two- 
spring arrangement eliminates this defect entirely, it forces the pen point 
to remain parallel to the center point; the angle to the drawing surface being 
constant no matter what the size of the circle may be. 

ALCO "CIRCLE A" DRAWING PENS 



The Ruling Pens are made of the finest quality of steel. The material 
used in Pens Nos. 1600 to 1602 being made especially hard, they are un- 
equalled for their extreme hardness and toughness. 

Lateral motion of the blades is entirely overcome in the pens by T-bolt 
screws. The screws move freely and can adjust themselves to the position 
of the blades. 

All Ruling Pens have metal handles.

Spring Dividers of the ordinary construction require considerable time 
in adjusting. This drawback is overcome in our instruments Nos. 1695-1 
to 1695-3 by an adjusting screw with notches at equal distances, by means 
of which they can at once be set for approximately the distance required, 
the final adjustment only being effected by the regulating screw.

ALCO "CIRCLE L" DRAWING INSTRUMENTS 

Each instrument stamped ALCO © 

Of finest hard rolled German silver, white wrought metal and 
highest grade tool steel. 



Features of the Compasses. 





Embodying improved pivot joint construction, head true and nicely 
fitted. Design does not permit of looseness. Patent clamp to lock instru- 
ment in any position. Straightening device to keep handle in perpendicular 
position at all times. 




Double Steel Knee Joint 



Slip Shank Fitting 



These features prevent looseness, increasing their durability to a very 
large degree. The insertion joints are nicely fitted and very strong, making 
the clamp screw almost unnecessary. 



THE PATENT NEEDLE ADJUSTMENT 

as embodied in our Alco "Circle L" Compasses and Bow Instru- 
ments offers an advantage which is self-evident. By its sim- 
plicity one can regulate the needle to a nicety and very much 
quicker than in -the old way. 

For very fine work this feature should prove invaluable, 
serving, as it does, the duty of a micrometer. 



THE DIVIDER POINTS 

are so made that they are readily interchanged or replaced by simply turn- 
ing the clamp screw, overcoming thereby the troublesome regrinding of the 
broken points.

Each instrument stamped ALCO © 

The Ruling Pens which constitute our ALCO "Circle L" line, both sep- 
arate and in sets, arc fitted with the patent Slide Catch feature. We firmly 
believe that of all the devices which have been attempted to aid the drafts- 
man in the opening and cleaning of the Ruling Pen this idea is the neatest, 
quickest and simplest of any yet devised. 




Open 




In order to open the pen (when closed) hold firmly, engaging the slide 
catch with thumb and in this manner the opening and closing is controlled; 
the latter by bringing pressure to bear as catch is slid forward. 




■^aCSlJS 



BOW INSTRUMENTS 



The innovation in design of these bow instruments lias eliminated the 
troublesome stripping of the threads. Being of spring construction with 
inserted left and right threaded nuts, the life of the bow is indefinite. The 
tension remains almost constant whereas the old form, due to unequal wear 
or strain, are soon worn out. Please note that the threaded ends of the 
center wheel never project beyond the side of the bow.

For Drawing Dotted, Straight and Circular Lines in any Desirable Thickness 




No. 1808 



point with micrometer screw is attached, 
diameter can be drawn. 



This Dotting Instrument is very prac- 
tical and most reliable. 

It consists of a German silver frame, 
on which runs a toothed guide wheel 
and in front of it a round-faced guide 
wheel, holding the instrument in a ver- 
tical position while in use. 

The Dotting Wheel is fastened to the 
axis of the toothed guide wheel by 
means of a screw and runs on the out- 
side of the frame, which admits of an 
easy interchanging of the different 
wheels. The numbered side of the Dot- 
ting Wheel must be placed towards the 
outside. 

The pen is attached to a lever, from 
which a ratchet projects, resting on the 
Dotting Wheel and causing the pen to 
rise and fall according to the notches 
in the Dotting Wheel. Care should be 
taken to adjust the ruling pen to the 
right position before using the instru- 
ment. 

For circular lines the instrument is 

slipped over the round bar and fastened 

by means of the screw on the handle, 

on the other end of which a needle 

The bar being 11 inches long, circles up to 21 inches

PLANIMETERS 

This very useful instrument, for obtaining areas, is so well known to the 
engineer that it hardly need be described in particular. A theoretical discus- 
sion of the principles underlying its operation will be found in almost any 
handbook on higher surveying. 

We submit the following instructions and examples for using these 
instruments: 

INSTRUCTIONS FOR USING PLANIMETERS ARRANGED FOR 

MEASURING AREAS IN SQUARE INCHES (OR OTHER 

SINGLE UNITS ONLY) 




Planimeters Nos. 2000 and 2001. (Illustrated on page 372) 

With needle point outside the diagram. Put the instrument on the draw- 
ing surface, set the tracing point F at any mark on the outline of the area, 
then press the needle point E slightly into the paper outside the curve, and 
read off the roller D and the counting wheel G, taking the whole circum- 
ference of the recording roller as the unit of the reading (the roller need not 
be set to zero). 

Readings. The drum of the roller is divided into 100 parts. The tenths 
of a part are read on the vernier. The complete turns of the roller are read 
on the counting disc, which advances one line at every complete turn. The 
counting disc performs one revolution at every 10 turns of the roller. 

Each complete reading is a figure of 4 digits, the units being read on the 
counting disc, the tenths and hundredths on a drum, and the thousandths on 
the vernier. 

The reading of the roller and disc, shown for example in the adjoining 
figure, is 5.343. 

(The zero of the drum and a mark of the disc should simultaneously be 
opposite the fixed index mark. This is never exactly the case in consequence 
of the imperfection of the worm wheel gear, and this should be taken into 
account in making readings in the same way as with a watch, when the 
minute hand points to 12, while the hour hand fails to indicate the exact 
hour.) 

Then move the tracing point F around the area in the direction of the 
movement of the hands of a watch till it reaches again the starting point. 
Now take another reading and subtract the first from the second reading. 
The difference multiplied by 10 will then be the area of the curve in square 
inches. 

Example: To measure the area of a square of 4-inch sides. 

Result: Second reading 3.073 
first reading — 1.473 



1.600 X 10 = 16 sq. ins.

SURVEYORS' INSTRUMENTS 



SAN FRANCISCO, U. S. A. 



PLANIMETERS 

If the reading, before starting, had been 9.521 then the reading after circum- 
scribing the same square as before would be 1.121. As the travel of the roller is in 
both cases the same, it is evident that the zero mark of the wheel has passed the 
fixed index mark' and that, consequently, the second reading has now to be supplied 
with one more digit on the left before substracting the first reading. Thus 
Complete second reading 11.121 
first reading — 9.521 



1.600 X 10 = 16 sq. ins. 

With needle point inside the diagram. Circumscribe the diagram with 
the tracing point in the direction of the movement of the hands of a watch, 
watching at the same time the counter in order to see whether the total 
rotation of the roller is a forward or a back motion. 

This preliminary rough operation being completed proceed as explained 
before, following the curve carefully with the tracing point. If the total 
rotation of the roller has been a forward motion, subtract the first from the 
second reading and add the difference to the figure engraved on the top of 
the small weight used for keeping the needle point in its place. The sum 
multiplied by 10 will then be the area of the curve in square inches. 

Example: To measure a circle of 18 inches in diameter. (You will see

NOTE. — When the mark o on the roller is at the mark o on the vernier 
a mark of the counting wheel should be opposite the fixed index mark. Any 
slight noncoincidence due to imperfection of worm wheel gear may readily 
be allowed for in taking readings. 

The area corresponding to a total revolution of the roller — 10 sq. ins. in 
the above example — is engraved on the weight along with the figure before 
mentioned.

PLANI METERS 

The divisions on the bar are the following: 
on back | 200 ac 6" = 1 mi | } °^ C J , : 2 ^°, | 5 ac 1 : 2500 

on top 20.811 20.818 21.042 

onfront| 100 ocm 1 100 □' 5 8 " = I'| Xn'^V | 10 ain | 400 a' X" -V 

(The figures on the top of the bar vary slightly for different instruments. The 
denotation o' means square foot, D cm = square centimeter, D in = square inch, 
ac = acre, mi = mile.) 

The slide being set on the bar, place the instrument upon the drawing 
and measure the diagram as with planimeter No. 2000. 

Example: To measure a circle of 5 inches in diameter on a ]4" plan. 

Set the index mark J on the slide to the division 200 □' ^" = 1', press the 
needle point E outside the circle into the paper, set the tracing point F to any mark 
of the circle, read off the counter — the reading may be 1.322 — follow the circle 
with the tracing point until you arrive at the starting point and read again the 
counter. The reading will then become 2.893. 

Result: Second reading 2.893 

first reading — 1.322 

1.S71 X 200 = 314.2 sq. ft. 

(The multiplier 200 is identical with the figure close to the right of the division 
used.) 

For measuring small diagrams drawn on the J^" or l /i" scale, the slide may 

conveniently be set to the last division on the bar marked .^r. ::, A,, ~ , , 

If the needle point E be placed inside the diagram to be measured, then one of 
the figures on the top of the bar must be used in the same way as the figure on the 
weight of planimeter No. 2000. 

Example : To measure a square of 1 2-inch sides on an ordinance map (scale 
1 : 2500). 

Set the index mark on the back of the slide to the division 10 ac 1 : 2500. 

Suppose that the counter reads 2.482 before starting the tracing point. 

In following the outline of the square you will see that the total rotation of the 
counter is backward and that the zero mark of the counting wheel passes the fixed 
index once. 

Result: Complete first reading 12.482 
second reading — 4.723

PLANIMETERS NOS. 2015-2022 

On these instruments the tracer arm is graduated, and settings can very 
accurately be made for any scale, either U. S. standard or foreign measure- 
ment, and allowances can be made for any shrinkage of the paper. The 
tracer arm also bears proportion marks for a number of scales for inches 
and metric measurements.

POLAR PLANIMETERS 




No. 2010 

No. 2010 Polar Planimeter, similar to No. 2005, but with special arrangement for 
rapidly finding the mean height of indicator diagrams (see explanation 
below). Range: Circle 25 in. in diameter; length of diagrams 2.8 in. In 
neat velvet-lined case, with instructions. Each $30.00 

Arrangement for Finding the Mean Height of Indicator Diagrams 



This arrange- 
ment consists of 
] two steel points 
(protected by metal 
caps when not in 
use) as shown in 
the adjoining illus- 
tration, one at- 
tached to the top 
of the tracer arm, 
the other to the 
top of the carriage. 



To obtain the mean height of the diagram, hold the instrument upside down, and by 
shifting the slide on the bar, adjust the two steel points so that they coincide exactly with the 
length of the diagram. Then place the planimeter without altering the relative position of 
slide and bar in the usual way upon the drawing — needle point outside the diagram — and 
follow the outline of the diagram with the tracing point. The difference of the readings at the 
beginning and at the end of the operation divided by 0.4 will be the mean height of the 
diagram, expressed in inches. 




Example: Second reading 
first reading 



2.361 
1.913 



0.4) 0.448 = 1.12 ins. = mean height. 

If the diagrams for up and down stroke are measured jointly, divide by . 8 
instead of 0.4. 

Mean pressure = Mean height X Scale of spring of indicator. Supposing the 
scale of the spring in the above example is 1 " = 80 lbs. per sq. in., then 

0.448 X 80 

Mean pressure = = 89 . 6 lbs. per sq. in. 

0.4 

The number of pounds per inch of height being usually a multiple of 4, the arithmetical 
work is thus extremely simple.

For prevailing prices see latest supplementary price list. 



COMPENSATING PLANIMETERS 

Compensating Planimeters Nos. 2020, 2021 and 2022 are in two separate 
parts: one is the tracer arm with measuring and recording wheels, the other 
the polar arm, having the pole weight at one end and a steel ball at the 
other, which forms a ball joint with the carriage. The ball joint cannot 
become loose or shaky, nor is it liable to be injured when adjusting the 
tracer arm or during shipment, as each part is stored in the case separately. 
This construction gives the tracer arm a motion of 180° in either direction, 
therefore the range of these instruments is much greater than that of the 
ordinary planimeters. 

The pole is so constructed as to combine the advantages of the pole plate 
and the needle point, as the point need not be pressed into the paper and 
may be used for setting the roller to zero without touching the measuring 
roller. 

By measuring a diagram with the pole on the right, and then on the left 
side of the tracer arm, and taking the mean of the readings all errors of the 
instrument are compensated.

THE ADJUSTABLE POLE ARM 




No. 2022 



The adjustable pole arm, extending to about 13 inches, bears index marks for the different 
settings furnished with the instrument, and can be adjusted so that when the instrument is 
used with the pole inside of a figure, the constant is a round number, 20,000 for any setting. 
The instrument is used in the same way with the pole inside as with the pole outside, and by 
tracing the figure with the pole on the right and on the left of the tracer arm (about 13 inches) 
and taking the mean of the readings, large areas can be measured with great accuracy. The 
extensibility of the pole arm and the great range of the tracer arm permit of measuring very 
large figures with the pole outside. By reducing the length of the pole and tracer arms, the 
instrument can be used in a very small space.

POLAR PLANIMETERS 




No. 2025 

No. 2025 Pantograph Polar Planimeter, German silver, with two adjustable tracer arms 
arranged for measuring areas in several units and scales. In neat velvet- 
lined case, with instructions. Each $65.00 

Pantograph Polar Planimeter is particularly well adapted for measuring very large or 
very small areas. The long tracer arm has a range of a circle about 38" in diameter. When 
using the long tracer arm it is advisable to remove the tracing point of the short arm, and the 
figure is traced in the usual manner. The short tracer arm is used for measuring very small 
areas. The tracing point is set on the figure, and the tracing point of the LONGER arm is so 
guided that the tracing point of the shorter arm follows the outline. As the two tracing points 
move alike, this is very easily manipulated. When using the short tracing arm in this manner 
the travel of the measuring wheel for the area is increased, in consequence of which the value 
of the wheel unit is smaller, and more accurate results are obtained. 




No. 2028 

No. 2028 Polar Disc Planimeter, German silver, adjustable tracer arm arranged for 
measuring areas in several units and scales. Range: Area enclosed between

case. Each , $75.00 

The Polar Disc Planimeter is especially useful when figures are traced on paper that has 
been folded, rolled, etc., as the measuring wheel revolves on a plane disc instead of over the 
paper being traced. The paper on the disc can easily be renewed at any time by removing the 
screw nut on top of the disc. More accurate results are thus obtained when tracing on paper 
where the surface has in any manner been damaged.

IMPROVED WILLIS PLANIMETER 




No. 2035 

No. 2035 Improved Willis Planimeter, in neat leather-covered case 

l^x3H x °^> complete with instructions. Each $25.00 

The Improved Willis Planimeter reads M. E. P. direct from indicator diagram, gives areas 
of regular or irregular circles or diagrams in square inches, feet and yards without any com- 
putation. 

The usual planimeter has a recording wheel whose axle is parallel to the tracer bar. This 
wheel scrapes along the paper for all movements parallel to the tracer bar, and records by 
rotating all movements perpendicular to it. The instrument to which we call attention acts 
on an entirely different principle. The wheel (W) rolls for all movements parallel to the tracer 
bar and its steel spindle glides beneath roller for all perpendicular movements. After tracing 
a figure the result is read from the scale next to the wheel; this scale being triangular, has six 
graduated edges, any one of which can be brought next to the wheel, thus permitting reading to 
be taken in the unit best suited to the work. 

The recording wheel of the improved Willis Planimeter is made of steel and has a sharp 
edge, which takes firm hold upon the paper or material upon which the instrument is operated, 
and the long steel shaft of this wheel glides freely beneath the rollers (R) and. (S). which 
practically bear the weight of the instrument, and makes it absolutely frictionless. This con- 
struction gives great ease of movement, and the instrument is handled as readily on a rough 
table as on the finest paper. As the rotary movement is not registered, it is apparent that the 
accuracy of the instrument is not affected by the character of the paper or material upon which 
the instrument is operated, or by any slight reduction of the diameter of the wheel or injury to 
the knife edge. This is one of the most important points to be considered in the selection of a 
planimeter.

MECHANICAL INTEGRATORS 

With the aid of these instruments it is possible to ascertain the area and 
moments relative to an axis of any figure, by simply tracing its outline. 
They greatly facilitate the finding of the displacement, moments of stability 
and inertia, center of gravity, etc., of ships, the tensile strength, resistance. 
safe load, etc., of tracks, cables, beams, contents of embankments, etc. The 
readings are taken from the recording discs. These instruments are very 
simple, and can be used by anybody after a little practice.

Amsler's Mechanical Integrators Nos. 2045 and 2046 are provided with 
two tracing points, for large and small figures. When using the one nearest 
to the center of rotation of the instrument, the travel of the measuring 
wheel is increased, as a consequence the area value of the wheel unit is 
smaller, and more accurate results are obtained. Very large figures can be 
measured in sections. By means of a formula furnished with each instru- 
ment, area and moment of figures drawn to scale can easily be obtained.

THE MECHANICAL INTEGRAPH 

The Integraph is an integrator which not only indicates the final result 
of the integration, but also gives a graphic representation thereof. While 
the tracer travels around the outline of the figure, the integraph automatically 
draws an integral curve the ordinates of which are proportionate to the 
area of the figure traveled around (vi =_/>'■ dx). If this first integral curve 
is traced by the tracer of the integraph as a differential curve, the tracer 
draws a second integral curve the ordinates of which are proportional to the 
moment of stability (yj =fy 2 dx). By tracing this second integral curve we 
obtain a third integral curve the ordinates of which are proportional to the 
moment of inertia (ys =/ y 3 dx) etc. The y-axis for the moments can be 
chosen anywhere on the curve, i. e., it can be shifted. By means of the 
integraph many of the most difficult calculations and problems occurring in 
the practice of an engineer can be solved in a simple and reliable manner and 
with much saving of time and the operator need not possess any knowledge 
of higher mathematics. 

The applications of the integraph are very numerous. With it we calcu- 
late areas, divide areas, determine centers of gravity, calculate moments of 
stability, load and resistance, solve algebraical equations, etc.

riages of the tracing and integrating points have a lateral travel of 10.3 
inches. The base can be set from 1.5 to 5.2 inches.

THE UNIVERSAL DRAFTING MACHINE 




Cut shows Mid-Anchor Machine 



The Universal Drafting Machine consists of two parallelograms, a protractor, and a 
square having graduated ruling edges. The blades of the square are interchangeable for all 
graduations. 

The two parallelograms joined together constitute an arm which, anchored to the board, 
gives the protractor and square a parallel motion about the drawing. This form of parallel 
motion permits either zero on the ruling edges to be instantly placed at any point on the 
drawing, by a single direct movement, and a line being drawn along the graduated ruling 
edge, just the exact length required. 

A conveniently arranged protractor permits the square to be set at any angle, and it then 
has the same parallel motion about the board as when set at zero.. Machines are furnished 
with either of the three following protractors: 

STANDARD PROTRACTOR. Has graduated arc allowing square to be set at any 
angle, and is provided with automatic stops allowing the square to be instantly set at 30°, 
45°, 60° and 90°, without stopping to read or clamp the protractor. 

ARCHITECTURAL AND STRUCTURAL PROTRACTOR. Special graduations are 
added to this protractor giving one-fifth, one-fourth and one-third roof pitches each way 
from zero, also special graduations to give two inches to the foot each way from zero. 

CIVIL ENGINEERS* PROTRACTOR. This protractor has two independent swinging 
motions, the same as on a transit. The protractor is graduated to one-half degrees and the 
vernier reads to minutes. With the aid of this protractor it is a simple matter to duplicate 
work (done in the field) on the drawing, directly from the field notes. 

HARDENED JOINT AND SOLID ROD DRAFTING MACHINES 

The Hardened Joint Solid Rod Drafting Machine is a development from the original 
construction of the Drafting Machine. Hardened, ground and polished straight cylindrical 
pins working in hardened, ground and polished bearings form the bearings of this machine, 
and if kept properly lubricated and free from dirt they will give many years of good service 
with no perceptible wear. 

BALL BEARING TUBULAR ROD DRAFTING MACHINES 

The Ball Bearing Tubular Rod Drafting Machine is an achievement that makes the 
Drafting Machine practically ideal. It has absolutely no play in the bearings and is fric- 
tionless. It is light in weight and possesses great rigidity, and is exceedingly accurate, and 
the motion is smooth and light.

DRAFTSMEN'S SCALES 

Ate* Quality 



We offer two types of scales: the Plain Boxwood and the White Edge, 
the latter a combination of boxwood and celluloid. Both are made of the 
finest materials and the wood is thoroughly seasoned. They are engine 
divided to United States standard measurements and the graduations are 
fine and clear and deeply cut. Both the Boxwood and the White Edge Scales 
are made in a variety of shapes, described as follows: 





Triangular Scales, Regular Shape. This type of scale 
has the advantage of possessing six surfaces and affords the 
greatest range of scales. 

Triangular Scales, Improved Shape. Like the regular 
shape, possess six surfaces but the concaved facet shape 
affords a better contact with the drawing and allows a 
better angle of vision. It prevents the divisions from 
wearing off by friction. 

Flat Scales, Regular Shape. The regular shape flat 
scales have two bevels for graduations. The graduations 
are more conveniently read than on the triangular scales. 

Flat Scales, Double Bevel. These scales have four bevels 
for graduations, but this shape necessitates the raising of 
the scale to bring the edge in close contact with the paper. 

Flat Scales, Opposite Bevel. This type of scale is an 
improvement on the regular flat scale as it presents but one 
graduated bevel to the eye. It is easily picked up or turned.

SCALES MADE TO ORDER 

We arc equipped to furnish special scales of all kinds, and in order to 
avoid mistakes or delay in prolonged corresponding we offer the following 
suggestions when ordering special scales: 

1 — State whether Boxwood or White Edge Scale is wanted. 
2 — State shape scale is to be. (See page 400.) 
3 — State length of scale wanted. 

•1 — How each edge is to be .graduated. State whether to be Open Divided 
or Full Divided. 

There are two distinctly different ways of graduating a scale: the Open 
Divided and the Full Divided Scale. 

The Open Divided Scales are generally used for architectural or mechan- 
ical drawing and are divided in inches or parts of inches, which represent 
feet or full inches. The units are graduated along the entire length and the 
end units only are subdivided to inches or fractions. 

When ordering a scale divided with different divisions, two to each edge, 
one of these must be the double of the other, as for instance, $4x1, \'/ 2 x3 or 
'Ax'/i. One of the divisions on each edge is then numbered from the right 
and one from the left. On an open divided scale with -but one division to 
each edge each scale is ordinarily numbered reading from right to left and 
from left to right, and each end unit is subdivided to inches or fractions. 

We can furnish the above scales, fully divided, to order if desired. 

The Full Divided Scales, or Chain Scales, as they are commonly called, 
are used mostly by surveyors or civil engineers. They are generally divided 
to decimals of inches or feet, and subdivided the entire length of the scale. 
Therefore it is possible to have only one division to each edge. They are 
usually numbered continuous every ten divisions, the triangular scales read- 
ing from left to right and the flat scales reading both ways, i. e., from left to 
right and from right to left. 

5 — State how each edge is to be numbered, from left to right or right to 
left or both ways. 

It is advisable when ordering special scales to furnish us a sketch. This 
need not be accurate. All that is necessary is to show the divisions as you 
want them, the length of the various graduation marks, and the numbering 
as it is wanted.

THE "INTERLOX" SLIDE RULE 



The Interlox Sliding Rule combines a rule for lineal measurements with a direct reading 
inside caliper rule. When closed, all the slides are locked together with an interlocking device. 
The first slide, when pulled out, releases the second slide, the second releases the third, and 
so on. This interlocking device makes it impossible to make any error in taking measurements 
as the slides cannot be extended or closed except in consecutive order. The closing is effected 
by pressing a key spring on the first slide which releases the second, the second the third, etc., 
until closed. 

Illustration shows rule in position for taking inside measurements. A direct reading of 
the distance between the two extreme points of the rule is obtained where indicated by arrow.

and the whole liner occupies but a space on the drawing board 854 ' n - long. 
The arm is perfectly rigid. An extra strong steel spring clutches the car- 
riage firmly at any point along the bar, so that there is positively no lost 
motion in any of its parts, although the pinching together of either left or 
right post and the lever forces it evenly and smoothly forward the distance 
of the setting. In operating, let us say from left to right, bring the car, by 
means of pressure, to the left-hand end of the base. Set the left indicator to 
the desired spacing, clamp firmly. Place the forefinger of the left hand on 
the knurled knob, the thumb on the lever. Press together, releasing first fore- 
finger, then the thumb. In reversing, or in this case, operating from right 
to left, set to the desired spacing, by means of the right-hand indicator, and 
proceed as before.

SLIDE RULES 

The Slide Rule is an indispensable aid to anyone who in his business is called upon to make calcula- 
tions. The principles with which one must be familiar are few and simple and are easily mastered with 
little practice. 

Abstract from Kent's Mechanical Engineers' Pocket Book, 9th Edition, 1916. 

The slide rule is based on the principles that the addition of logarithms multiplies the numbers which 
they represent, and subtracting logarithms divides the numbers. By its use the operations of multiplica- 
tion, division, the finding of powers and the extraction of roots, may be performed rapidly and with an ap- 
proximation to accuracy which is sufficient for many purposes. With a good 10-inch Mannheim rule the 
results obtained are usually accurate to i of 1 per cent. Much greater accuracy is obtained with cylin- 
drical rules like the Thacher. 

The rule consists of a fixed and a sliding part both of which are ruled with logarithmic scales; that is, 
with consecutive divisions spaced not equally, as in an ordinary scale, but in proportion to the logarithms 
of a series of numbers from 1 to 10. By moving the slide to the right or left the logarithms are added or 
subtracted, and multiplication or division of the numbers thereby effected. The scales on the fixed part 
of the rule are known as the A and D scales, and those on the slide as the B and C scales. A and B are the 
upper and C and D are the lower scales. The A and B scales are each divided into two, left hand and right 
hand, each being a reproduction, one half the size, of the C and D scales. A "runner," which consists of a 
framed glass plate with a fine vertical line on it, iB uBed to facilitate some of the operations. The numbering 
on each scale begins with the figure 1, which is called the "index" of the scale. In using the scale the figures 
1, 2, 3, etc., are to be taken either as representing these numbers, or as 10, 20, 30, etc., 100, 200, 300, etc., 
0.1, 0.2, 0.3, etc., that is, the numbers multiplied or divided by 10, 100, etc., as may be most convenient 
for the solution of a given problem. 

The following examples will give an idea of the method of using the slide rule. 

Pro-portion. — Set the first term of a proportion on the C scale opposite the second term on the D Bcale, 
then opposite the third term on the C scale read the fourth term on the D scale. 

Example. — Find the fourth term in the proportion 12 : 21 :: 30 : z. Move the slide to the right until 
12 on C concides with 21 on D, then opposite 30 on C read x on D ■= 52.5. The A and B scales may be used 
instead of C and D. 

Multiplication . — Set the index or figure 1 of the C scale to one of the factors on D. 

Example. — 25X3. Move the slide to the right until the left index of C coincides with 25 on the D 
scale. Under 3 on the C scale will be found the product on the D scale, = 75. 

Division. — Place the divisor on C opposite the dividend on D, and the quotient will be found on D 
under the index of C. 

Example.— 750 -5- 25. Move the slide to the right until 25 on C coincides with 750 on Z). Under the 
left index of C is found the quotient on D, = 30. 

Combined Multiplication and Division. — Arrange the factors to be multiplied and divided in the form 
of a fraction with one more factor in the numerator than in the denominator, supplying the factor 1 if 
necessary. Then perform alternate division and multiplication, using the runner to indicate the several 
partial results. 

4X5X8 

Example. =8.9 nearly. Set 3 on C over 4 on D, set runner to 5 on C, then Bet 6 on C under 

3X6 
the runner, and read under 8 on C the result 8.9 — on D. 

Involution and Evolution. — The numbers on scales A and B are the squares of their coinciding numbers 
on the scales C and D, and also the numbers on scales C and D are the square roots of their coinciding num- 
bers on scales A and B . 

Example. — 4*= 16. Set the runner over 4 on scale D and read 16 on A. 

y 16 = 4. Set the runner over 16 on A and read 4 on D. 

In extracting square roots, if the number of digits is odd, take the number on the left-hand scale of 
A', if the number of digits is even, take the number on the right-hand scale of A. 

To cube a number, perform the operations of squaring and multiplication. 

Example. — 2'= 8. Set the index of C over 2 on D, and above 2 on B read the result 8 on A. 

Extraction of the Cube Root. — Set the runner over the number on A, then move the slide until there is 
found under the runner on B, the same number which is found under the index of C on D; this number 
is the cube root desired. 

Example. — y8 = 2. Set the runner over 8 on A, move the slide along until the same number 
appears under the runner on B and under the index of Con D; this will be the number 2. 

Trigonometrical Computations. — On the under side of the slide (which is reversible) are placed three 
scales, a scale of natural sines marked S, a scale of natural tangents marked T, and between these a scale 
of equal parts. To use these scales, reverse the slide, bringing its under side to the top. Coinciding with 
an angle on S its sine will be found on A, and coinciding with an angle on T will be found the tangent on 
D. Sines and tangents can be multiplied or divided like numbers.

No. 2970 Junior Mannheim Slide Rule, 5 in, long, mahogany stock with white cellu- 
loid facings. Graduations engine divided, with magnifier. In sewed leather 
case with instructions $4.50 

The Junior Mannheim Slide Rule No. 2970 combines the accuracy of a regular 10-inch 
slide rule with the convenience afforded by its compactness. The subdivisions are as fine as 
those on a regular 10-inch rule, and by means of a neat but powerful magnifying glass 
attached to the indicator their value is easily ascertained with the same degree of accuracy as 
can be obtained on the larger rule.

THE POLYPHASE SLIDE RULE 

Best Quality Adjustable 




The Polyphase Slide Rule has in addition to the regular scales of the Mannheim Rule a 
scale of cubes on the edge of the rule and an inverted scale through the center of the slide. 
These scales may be used in connection with the others, by means of the indicator. The 
inverted scale enables taking three factors at one setting of the slide, and reading reciprocals 
by means of the indicator. Almost any combination of three factors involving square, 
square root, cube and cube root may be solved at one setting of the slide. 

Rutes are engine divided on white celluloid facings. The divisions are clear, distinct, 
permanent and accurate.

Each 14.00 



THE PRECISION SLIDE RULE 




The Precision Slide Rules are similar to other Mannheim Slide Rules, but the results 
obtained are of a considerably greater accuracy. The increase in accuracy is obtained by 
making the scale length of the logarithmic unit equal to 50 cm. instead of 12.5 cm or 25 cm. 
The scale is not, however, made in one length of 50 cm. but in two lengths of 25 cm. each. 
All the other scales, including those on the back of the slide, are based on the scale length 
of 50 cm.; so that all calculations with this slide rule have a uniform and considerably greater 
degree of accuracy than those made with the ordinary slide rule. 

Rules are engine divided on white celluloid facings. The divisions are clear, distinct, 
permanent and accurate.

THE ALCO SLIDE RULE 




This Slide Rule differs from those hitherto ordinarily employed in that it 
has on its front face not only the four middle scales (two on the rule A and 
D; and two on the slide B and C), but also two other scales, viz., an evenly 
divided scale E, on the lower margin, and a logarithmic scale F, at the top, 
the latter consisting of three similar scales, placed consecutively. 

By this arrangement, logarithms, cubes and cube roots can be directly 
and easily determined. With the ordinary slide rules these calculations, 
especially the extraction of cube roots, are somewhat complicated, and 
necessitate the use of the slide. 

All calculations such as multiplication, division, involution, evolution, etc., 
are carried out with the first mentioned scales, A, B, C, D. 

Engine divided on white celluloid facings. The divisions are clear, 
distinct, permanent and accurate.

Especially evolved in response to a demand for a suitable Slide Rule for 
Electrical Engineers and for students in Electro-Technology. 

Serves in an excellent manner the facility of calculation of all electro- 
technological problems. The table of constants, on the reverse of the rule, 
makes the reference to hand-books almost superfluous.

HAZEN-WILLIAMS HYDRAULIC SLIDE RULE 






' 4 i. .' — - . 



No. 3044 

The Hazen-Williams Hydraulic Slide Rule is used principally for deter- 
mining the velocity and quantity of the flow of water in pipes and channels, 
but is also adapted for ordinary slide rule calculations. Special computations 
may also be solved by its use, as, for instance, to determine the corresponding 
flow at any other slope or head, when the flow of water through a pipe or 
"system of pipes produced by a given slope or head is known; to find what 
size of pipe must be used to produce the same discharge for any other slope, 
when the discharge in a given size of pipe at a given slope is known; to com- 
pute the discharge through a compound pipe, that is, a pipe of larger diameter 
connecting with a pipe of smaller diameter, or a series of such pipes; to 
compute the friction of a given amount of water flowing through two pipes 
of different diameters and different lengths, freely connected at each end; to 
get with one setting of the slide the quantity of water corresponding to any 
slope; to get with one setting of the slide the quantities of water discharged 
by pipes of different sizes for a given slope and coefficient. In size and gen- 
eral appearance the rule is like an ordinary Mannheim 10-inch slide rule. On 
the back of the rule are several tables to aid in the convenience of computa- 
tions to which the rule is applicable. Engine divided on white celluloid 
facings. The divisions are clear, distinct, permanent and accurate.

THE SPITZGLASS SLIDE RULE AND FLOW COMPUTER 

The Spitzglass Slide Rule will solve quickly and simply all problems in- 
volving the flow of fluids in pipes with a greater amount of accuracy than 
results obtained by other formulas, as the rule is based on new experimental 
data. It will also accomplish all ordinary slide rule calculations. The rule is 
made of solid seasoned white celluloid, fastened to a durable leather folding 
case, convenient for the pocket. The graduations are engine divided and are 
clear, distinct, permanent and accurate.

This is a very compact, convenient and accurate 
instrument and very simple to operate. It is made 
entirely of metal and its construction is extremely 
simple, so that it is impossible for the instrument 
to get out of order. 

The book of rules accompanying each instru- 
ment is most extensive and complete, yet very clear 
and easy to understand. It has been arranged so 
as to fit in a separate compartment of the leather 
case containing the instrument, so that both to- 
gether can be conveniently carried in the vest 
pocket. 

The Calculex, briefly described, consists of a 
disc within a fixed ring, which together form a dial 
with logarithmic scales on both sides, surrounded 
by a metal ring and protected on both sides by a 
glass rim with an indicator hair line marked there- 
on. 

The instrument is operated by turning the disc, 
holding the nut on either side between finger and 
thumb. The outside ring is fastened to the rim. 

Logs of numbers, squares, square roots, cubes, 
cube roots, angles, can be read direct from the in- 
dicator line, without turning the disc. 
No. 3075 T° e ^ont face contains five circles of scales. 

The outer scale No. 1 is a scale of Logs; Nos. 2 
and 3 are the calculating scales A and B, Nos. 4

Absolute accurate. Adapted to all conditions. Load, spacing, span, etc., 
found instantly. Mistakes absolutely eliminated. 

The Merritt Beam Scale for computing the strength of steel beams is based on the prin- 
ciple of the Engineer's Slide Rule and was designed to simplify computations of this kind, 
and to eliminate all chance of errors. Tables and formulae are absolutely unnecessary when 
the Merritt Beam Scale is used, and the speed with which answers to widely varying prob- 
lems may be solved can hardly be appreciated by anyone who has not had the pleasure of 
using it.

For computing the strength of wooden beams. Absolutely accurate. 
Adapted to all conditions. Load, spacing, span, etc., found instantly. Mis- 
takes absolutely eliminated. 

To illustrate the simplicity of the Scale the following is given: 

How far apart shall 6 in. x 12 in. timbers of white oak be placed to safely support a load 
of 150 pounds per square foot, the span being 18 feet, and New York law governing the design? 

Select the fibre stress for white oak allowed in New York City (given on back of scale: 
1000 pounds). Place 12 in scale B below 6 in scale A. Place 1000 in scale E over ISO in 
scale F. Above 18 in scale D read 2 ft.-0 in. in scale C. 

The Wager Timber Scale, for computing the strength of wooden beams, contains more 
information than could be given in 500 pages of tables. It is based on the principle of the 
Engineer's Slide Rule, and five minutes' inspection will convince anyone that it is simplicity 
itself.

Thacher's Calculating Instrument is a device for performing a great variety of useful 
arithmetical calculations with rapidity and accuracy. Its operation is simple and readily 
learned. By its use the tedious drudgery of calculation is avoided and the chance of error 
eliminated. 

As is shown in the illustration, the instrument consists of a cylinder 4 inches in diameter 
and 18 inches long, which revolves in an open framework composed of 20 angular bars held 
between two metal rings. The cylinder bears a scale corrsponding to the scale of the Slide 
Rule, which is duplicated on the exposed sides of the bars. Results can be obtained to the 
fourth and usually to the fifth place of figures with a surprising degree of accuracy, sufficient 
for nearly every requirement of the professional or business man. Examples in multiplication, 
division, proportion, powers or roots involving not more than three quantities, are solved by 
one operation, and any number of values of an algebraic function composed of two constants 
and a single variable may generally be found by one setting. 

The useful applications of the instrument are almost unlimited; among them may be men- 
tioned finding the stresses and sections in trusses and girders, mensuration, estimates of work 
and material, solving trigonometrical formulas, making and applying tables, problems in 
mechanical powers, machinery and hydraulics, problems in simple and compound interest, dis- 
count, prorating, the conversion of weights and measures, cost of merchandise with per cent 
of duty or profit added. 



FULLER'S SLIDE RULE 




No. 3103 



No. 3103 Fuller's Spiral Slide Rule, in mahogany box with directions $30.00 

Fuller's Spiral Slide Rule consists of a cylinder which can be moved up or down and 
turned round a sleeve which is attached to the handle. A single logarithmic scale, 42 feet 
long, is wound round the cylinder spirally, and ratios are established by means of two pointers 
or indices, one attached to the handle and the other to an axis which slides in the sleeve.

STADIA COMPUTORS 

No. 3104 Cox Stadia Computor $075 

The Cox Stadia Computor is a circular slide rule of about 15 inches effective length for 
the reduction of stadia readings. Printed on heavy cardboard, cloth bound, size 6!4x6J4, 
suitable for carrying in coat pocket.

_J 



No. 3105 



The use of this Stadia Reducer involves the using 
of only such vertical angles as may be read without 
the use of the vernier, and taking the vertical difference 
and horizontal distance directly from the Reducer 
slide. Results are given for these angles up to 30 de- 
grees. The height cut on the rod by the middle wire 
is noted for a correction. 

The setting of the telescope to an angle marked by 
an even division on the arc can be quickly and ac- 
curately made with small chance of error, but if 
desired the observer may mark one side of the arc and 
let the distinguishing sign appear in the notes. For 
example, he may mark the minus side red and then 
an angle of — 10° could read red 10°. 

The results given by the Reducer are those obtained 
by the well-known stadia formula; where S = the stadia 
distance, V = the measured vertical angle, D = the 
horizontal distance and H = the distance of elevation 
to the point sighted on the rod. Then D = (S -\- f -|- c) 
cos 2 V and H = (S -f- f + c) # sin. 2 V. These 
formula? are practically correct for vertical heights up 
to 15° and give results too small from 15° up to 30° 
by the amounts given in the following table. Horizontal 
distances are given practically correct up to 30°: 
Angle of inclination 1S° 20° 23° 25° 27° 29° 30° 
Error in vertical 

heights 0.01 0.02 0.03 0.04 0.05 0.06 0.07 

These small quantities may be neglected in practice. 

Stadia Reductions 



After obtaining the stadia distance either by care- 
fully adjusted wires or by a ratio table previously pre- 
pared, add the f + c for obtaining the distance argu- 
ment to be noted on the top of the Reducer case. Incline the telescope to the nearest division 
on the vertical arc that will keep the middle wire on the rod, and note the rod reading that 
the middle wire cuts for a final correction. Pull out the Reducer slide until the angle of arc 
setting shows just above the case. On this same line on the slide and just above the distance 
argument on the case find the difference of elevation to the noted rod reading cut by the 
middle wire. Correct this by the rod reading to obtain the difference of elevation to the 
station occupied by the rod. Without moving the slide find the horizontal distance on the 
reverse side. 

These tables are also to be used after the manner of using a traverse table. For example: 
Suppose the distance argument is 962 and the telescope is afterward inclined to an arc reading 
of — 11° at which angle the middle wire cuts the rod at 7.21. A foresight computation would 
then be as follows: 

ON THE REVERSE SIDE 

For 900 867.2 

For 60 57.8 

For 2 1.9 



ON THE FRONT SIDE 














—7.21 


Difference in elev. to station 


—187.39 



Horizontal distance 926.0 

The Reducer admits of being used to carry out the decimals further than is shown in the 
examples if greater accuracy is desired.

THE MARCHANT CALCULATOR 





HE value and importance of a first-class and trustworthy calcu- 
lating machine to the civil engineer, construction engineer, 
statistician and others who have considerable figure work to 
handle has long been conceded. 

Such a machine is a great labor and time saver, while the 
relief it affords from wearying brain work is incalculable. 
The Marchant Calculator (illustrated above) has met this long-felt want 
and has filled the requirements and demands of engineers and statisticians 
the world over. 

Pencil and slide-rule methods of figuring problems are fast becoming 
obsolete. The up-to-date mining or construction company can no longer 
afford to have its employees spending time in unnecessary hand figuring 
when machine calculation has been perfected to such a degree as in the 
Marchant Calculator. 

The Marchant is built on the rotary or drum principle. This principle 

can be appreciated by technical men as the best for direct action functioning. 

By using the drum principle all unnecessary action is eliminated, thus 

insuring a minimum of expense in upkeep — springs, cams and other parts 

used in machines of the flat-bed principle being entirely done away with. 

Operation 

Unlike many of the machines on the market at the present time, the 
operation of the Marchant can be explained and taught to the novice in a 
very short time, it being unnecessary to engage a special operator to per- 
form even the most intricate problems — the Marchant motto being "Do it 
yourself on a Marchant." 

Proof 

Every calculation performed on a Marchant is instantly proved, no 
hidden complements to memorize, each factor and result is at all times 
visible to the operator. It has been found that the proof feature saves 
100 per cent of the time spent on rechecking, as is often the case when using 
the old method of logarithms. Time and absolute accuracy are big features 
and important ones when engineers are crowded with work.

THE MARCHANT CALCULATOR 

Models 

The latest model Marcliant, namely the Pony, was built with the idea of 
producing a light, compact calculator of such convenient size that it could 
be taken to the job or moved about as a piece of hand baggage, and yet 
having all the well-known features of the standard model. 

The Pony Model is built in two styles — with and without the top register 
dial. The top register dial gives a complete check on all figures operating 
on levers, a feature not to be overlooked by the engineer who is constantly 
using constant multipliers and divisors. 

Application 

The Marchant will handle, in a fraction of the time ordinarily spent, all 
kinds of engineering calculations. Traverses, averages, square root, cube 
root, assays, assessments, formulae and tonnages can all be handled with 
rapidity. A typical problem of the mining industry with which the average 
engineer comes in contact can be explained thus: 

DISTRIBUTION OF METALS 
6948.82 tons ore assays as follows: 

0.129 oz. gold per ton. 
5.72 oz. silver per ton. 
3.225% copper. 

Weights Value 

6948.82x0.129 = 896.398 oz. gold. 896.398 x20.6718 = $18530.16. 

6948.82x5.72 = 39747.25 oz. silver. 39747.25 x 689 = $27385.86. 

3.225% of 2000 lb. = 64.5 lb. per ton. 448198.89x0.155 = $69470.83. 
6948.82x64.5 lb. = 448198.89 lb. copper. 

SURVEYING CALCULATION 

Bearing 34° 36' E. distance 295.76. 
Nat. cosine 0.82314; sine 0.56784. 
0.82314x295.76 = 243.452 northing. 
0.56784 x 295.76 = 167.944 easting. 

This traverse can be figured easily on a Marchant in forty seconds. 

Operation: Place distance or 295.76 on machine as constant and multiply 
by .82314. Leave figures on machine and interchange multiplier to .56784, 
getting second result. Point off seven decimal places (5+2). 

A fine testimonial from one of our largest users has this to say: 

"The machine proved itself so valuable in making up our cost statements 

and in verifying ore statements that we purchased five more Merchants. 

These are used by our engineers in all calculations pertaining to tonnages, 

averages, assays and percentages. 

(Signed) "UTAH COPPER CO." 

Some of the largest mining and engineering firms in this country and 
foreign lands are using the Marchant every day on their problems. 

Among prominent users the Marchant numbers as its endorsers: Utah 
Iron and Steel Co., American Smelting and Refining Co., International 
Smelting Co., Ray Consolidated Copper, Chino Copper. 

Our representative will deem it a pleasure to demonstrate the wide scope 
of flexibility of the Marchant. Descriptive literature and prices on request.

TRANSPARENT LETTERING ANGLES 




The Lettering Angles are de- 
signed to give a quick and easy 
method of making accurately spaced 
guide lines for lettering drawings. 

There are six columns of holes, 
the columns being subdivided into 
groups of three holes, the holes of 
each group being joined by scored 
lines. The figure under each col- 
umn denotes the height of the stand- 
ard capital letters in thirty-seconds 
of an inch. The standard spacings 
between groups, also for the lower 
case letters, are two-thirds the height 
of capitals. The purpose of three 
holes in each group is to enable the 
drawing of three guide lines for 
each line of lettering, when it is de- 
sired to use both lower case and 
capital letters. 

The Lettering Angle is designed 
to slide on the hypotenuse when 
making standard spacings, but either 
of the other two sides may be used 
to get other spacings. 

To use Lettering Angle, place the 
pencil point through a hole in the 
desired group, and slide along the 
T-square or another triangle; then 
place the pencil point through an- 
other hole and slide back. The Let- 
tering Angle is moved along very 
easily by the pencil. The tapered 
holes prevent the breaking of the 
pencil point. The guide lines will 
be very accurately spaced, and 
drawn much more rapidly than by 
laying off with scale or dividers. 

The lines scored across the Let- 
tering Angle enable one to obtain 
angles of 15°, 30°, 45°, 60°, 75° 
and 90° from either a 45° or 60° 
triangle, by setting these scored lines 
on horizontal or perpendicular lines 
on the drawing board. The lines 
drawn at right angles and parallel 
to the hypotenuse are particularly 
valuable when sketching or doing 
work without the use of the 
T-square, because it facilitates very 
much the drawing of one line at 
right angles to another. These lines 
being scored on the under side of 



Lettering Angle, throw no shadow, whereas the edge of the Lettering Angle does. 
The bevel pickup makes the Lettering Angle very easy to handle,

The Parallel Straightedge consists of a set of two double pulleys 
attached to the back corners of the drawing board, and two single pulleys 
attached to the front corners. A steel piano wire is placed around these 
pulleys, making a double lap along each end and back of the board but no 
wire across the front. By crossing the wire at the back, the upper laps at 
both ends must move forward and back simultaneously. 

The ends of the wire are joined together at the back through a steel 
spring. Both ends of the straightedge are attached to the upper wires at 
the ends of the board by binding posts, thus making it possible to move one 
end of the straightedge without moving the other a corresponding amount 
in the same direction. 

All pulleys, brackets and binding posts are made of brass, accurately 
machined, highly polished, and lacquer finished.

The board is lightly constructed and may easily be carried in a suitcase. It 
is reinforced on the under side with cleats, one at each end, to prevent it 
from warping. When not in use the triangles and T-square are held firmly 
in place, by means of a small metal spring, under one of the end cleats. An

The Hoffman Artist's Drawing Stand No. 3505 and Drawing Board Bracket No. 3507 are

and handsomely finished in nickel and black enamel, making a very attractive and most useful

By means of the Drawing Board Bracket No. 3507 a drawing board may be attached to 
anything that has a clamping edge, while the Artist's Stand No. 3505 has a tripod, which 
makes it complete in itself. Either the bracket or the stand may be purchased and later one 
converted into the other by adding the tripod or the clamp to the equipment. 

With either arrangement the drawing board can be adjusted instantly to any desired 
height, tilted and locked at any angle, from horizontal to vertical, and revolved. The outfits 
are light and easily transferred from office to home or the field. After removing three nuts 
from the brace which connects the tripod it will fold and pack in the box, 4^x5x24 inches.

THE "AVALON" DRAWING TABLE 

With Roller Adjustment 




No. 3520 



The Avalon Drawing Table is very substantial and rigid. It is 36 inches high and can be 
raised to 48 inches. This can be accomplished by turning the large handwheel. The slides are 
carried between roller bearings on the standards, and move with perfect freedom from friction, 
and without the grating sound of sliding metal surfaces. 

The slides may be locked at any desired height, by means of a hand nut easily reached by 
one hand while the wheel is being manipulated by the other. The tightening of this nut 
releases the inner roller and substitutes a frictional bearing on bases attached to the standards, 
forming an efficient clamp. In addition, by the same operation, the ends of the pinions are 
locked against the faces of the slides, rendering their revolution impossible and doubling the 
security of the clamp. 

Prices include best quality pinewood Drawing Board No. 3450.

THE DREW METHOD FILING CABINET 

The Drew Method of Filing as manufactured by us was primarily 
conceived to overcome the lost floor space as occupied by the drawer 
method and the inconvenience of taking drawings therefrom. Compact- 
ness and accessibility are paramount. The drawer method of filing needs 
no mention from us as to its faults, for anyone who has had to resort to 
maps or drawings when filed in this manner knows of its shortcomings. 
It can today only be regarded as obsolete. 




Maps may be altered without detaching. 
No. 3590— Illustration 1. 

The Drew Method Filing Cabinet consists of a Cabinet 5 feet 10 inches 
high and 15 inches deep, on which sections 18 or 36 inches in height may 
be added as additional filing space is required. 

The maps are attached to detachable spring rollers, or thin tracing paper 
sketches can be conveniently filed in metal containers. An idea of the 
filing capacity of the Drew Method Filing Cabinet can be gained when one 
realizes how easily 15 maps of varying sizes and lengths can be mounted 
in juxtaposition on each roller. When required the desired map can be 
drawn from its position on the roller for examination, which the other maps 
on the same roller will fall automatically out of the way. The front of the 
cabinet, when lowered, serves as a table, on which the maps may con- 
veniently be examined or altered, without detaching from the roller. When 
fully wound, the maps are kept from unraveling by means of metal spring 
clamps. 

Thin tracing paper sketches are filed in the metal containers and can 
easily be taken out for examination by means of pull-cords which slip under 
the tracings. 

The rollers and metal containers are made in two standard widths, 45 
and 60 inches, and are hung about 5 inches apart on two endless chains 
which revolve on geared wheels, so that any roller or container can be 
instantly brought in position for examination. The rollers and metal con- 
tainers are interchangeable and the desired number of each can be furnished.

THE DREW METHOD FILING CABINET 



Illustration No. 2 shows Drew 
Method Filing Cabinet when closed. 
This cabinet is 5 ft. 10 in. high, on 
top of which rests a section 18 in. 
high. Extra units may be added 
to admit the heightening of the 
cabinet when additional rollers are 
needed. 

The cabinet as shown embodies 
36 rollers, on which maps of vary- 
ing sizes and lengths can be 
mounted. 




Illustration No. 2 



Illustration No. 3 shows how 
conveniently the Drew Method 
Filing Cabinet is lowered or 
closed. The table drop is coun- 
ter-balanced by heavy springs, 
which control its action. When 
fully opened the front of the 
cabinet serves as a table con- 
sisting of a pinewood board on 
which alterations may be made 
to maps without detaching them 
from the rollers. The table may 
be enlarged by bringing the 
folding leaf into a lateral posi- 
tion, where it is firmly held by 
means of the two hinged sup- 
ports. A footrest is also in- 
serted for convenience wher, 
working about the cabinet.

The cabinets are built of either wood or steel and can be finished to 
match the general scheme of an office.

which is made of pinewood, 
serves as a drawing board. The 
convenience of this is self-evi- 
dent when one considers the 
necessity of finding a suitable 
place in the average office for 
doing a similar work, in fact the 
Drew Method Filing Cabinet 
eliminates the need of another 
drawing table. 

Investigate the merits of the 
Drew Method Filing Cabinets. 



Illustration No. 4 shows the 
Drew Method Filing Cabinet 

fully opened and in use. A long 
profile is drawn from its posi- 
tion on the roller for examina- 
tion or alteration. The springs 
in the rollers will admit of the 
carrying of maps fully 25 feet 
long, which may be stopped 
(like a window shade) at any 
place in the length.

THE BAXTER FILING SYSTEM 

This system of filing of drawings was brought forth by F. K. Baxter, 
of one of the Oil Companies of California. 

Confronted with the old problem of limiting the space required for the 
filing of the company's drawings, Mr. Baxter set about to conceive a method 
of throwing out, rather than adding to, the already large number of drawing 
cabinets in use by the company; floor and room space was in demand and 
limited. Necessity certainly proved the mother of invention in this instance. 

The illustration on opposite page shows over 1600 drawings of all sizes, 
lengths and widths most conveniently hung in place. The drawings, nega- 
tives or tracings are reinforced at the upper end with strips of heavy gummed 
paper, which will support the heaviest maps without tearing, suitably 
punched to be placed on pins suspended on rods fastened to traveling 
carriages about 12 inches wide when closed and in series, permitting of a 
separation to allow for the examination of the maps, thus affording acces- 
sibility to the cabinet, as shown in illustration. 

Invariably one wishes but to examine a drawing for the purpose of 
ascertaining the location of some property or bearing. It is only necessary 
to run the hand between drawing and the adjoining sheet (after locating the 
desired copy by means of the index) to examine it at will or without in- 
terference. 

But should it be necessary to take the map from its place in the cabinet, 
the gun-shaped hand (standing at end against folding door shown in illus- 
tration) is inserted in back of the desired map and a small locking pin is 
pulled down, opening the carriage. The maps on the one side remain locked 
on the carriage by means of the gun-shaped hand while the rest travel 
away from it. The map is then brought forth to be printed, examined or 
retraced, as the case may necessitate. An index card is placed in the rack 
in lieu of the map, on which is noted the whereabouts of the map proper. 
When the map is no longer required, it is placed upon a suitable rack at end 
of cabinet (as shown in illustration) until evening, when all are readily 
placed in their proper location in the file, the person filing being guided by 
the index number on the edge of the drawings. 

A curtain shade is drawn down over the whole when not in use, the folding 
iron gate is swung into place and the cabinet containing all the valuable 
drawings is secure against molestation. 

State your required capacity, the dimensions of your allowable or 
suitable space and we will work out your problem and quote you accordingly.

The carriages can be purchased with required length of track singly 
or in series, to which others can be added later, making it possible to install 
them in vaults or other fireproof compartments. We can also quote the

TRIANGULAR POINTS A <<^ 



The Worth Lettering Pen is the most recent innovation in pens par- 
ticularly intended for the lettering of maps or the writing of showcards, 
price tags, etc. The large capacity of the ink reservoir makes it superior 
for drawing heavy border or long contour lines without refilling. 

The improvements of the Worth Pen consist primarily of the inter- 
changeability of the pen points, the convenient method of filling and the 
rapidity with which it is cleaned. 

The triangular shaped point finishes each letter with a square edge. 

The Worth Lettering Pens are sold either separately or in sets, con- 
sisting of one holder and six different size nibs, as per above illustration.

Nos. 4121-4125 



The Bourgeois French Water Colors are put up in glass jars 
containing more than twice as much as the whole pans sold by other 
manufacturers at about the same price. They are moist and a slight 
rubbing of the desired colors with a moistened brush is sufficient to 
obtain the full richness of their tint. The colors are very brilliant 
in tone.

This volume contains a number of computing diagrams giving rapid, 
approximate solution of the common problems in the design and con- 
struction of electric power systems and similar undertakings. Beginning 
with the design of foundations, arches and reinforced concrete walls, the 
strength and dimensions of all necessary material can be readily deter- 
mined. Stadia readings can be quickly reduced, the capacity of pipes and 
flumes easily found, the economic size of pipe selected and the weight of 
material for wood-stave or steel pipe lines determined. Where steam is to 
be used the horsepower of different sized engines can be mechanically 
determined and the power transmitted by shafting, gearing and belting 
calculated. Electric wiring problems and those of pole line construction are 
worked simply and the comparative cost of power easily shown. All this 
and more may be done without knowledge of mathematics by the simplest 
mechanical process; no handbook nor slide rule nor table of logarithms is 
necessary in any of the problems covered. Detailed explanations and typical 
examples are given on the page opposite each of the diagrams.
